CHAPTER 2 - GENERAL INFORMATION

2.3 ABOUT THE CFW-08 TThe CFW-08 VFD provides two control options: vectorcontrol (VVC: voltage vector control) or V/Hz (scalar); bothtypes of control can be set according to the application.

In thevector control mode, themotor performance is optimizedrelating to torque and speed regulation.The "Self-Tuning" function, available in vector control, permitsthe automatic setting of the inverter parameter from theidentification (also automatic) of the parameters of the motorconnected at the inverter output.

The V/F (scalar) mode is recommended for more simpleapplications such as pump and fan drives. In these cases onecan reduce the motor and inverter losses by using the"Quadratic V/F" option, that results in energy saving.The V/F mode is also used when more than one motor shouldbe driven simultaneously by one inverter (multimotorapplication).

There are two CFW-08 versions:Standard: it has 4 digital inputs (DIs), 1 analog input (AI) and1 relay output.CFW-08 Plus: compared to the standard version it has oneadditional analog input and one additional relay output. It hasalso an analog output (AO).

For power ratings and further technical information, seeChaper 9.

Product AppearanceBesides the internal electronics, also the exterrnal productappearance have changed, which are:- The frontal lettering on the plastic covers (formerly: line,now: CFW-08 vector inverter);- WEG logois now indicated onall accessories of theCFW-08line (keypad, communication modules etc).

Figure below makes a comparison:

2.3.1 Differences between theold line andthe new CFW-08

Figure 2.4 a) b) - Comparison between line a CFW-08 appearance

Version of SoftwareThenew CFW-08 starts with Software Version V3.00. Thus,the software versions V1.xx and V2.xx are exclusive forline.Besides the inverter control has been implemented in aDSP (Digital Signal Processor), which enables a moresophisticated control with more parameters and functions.

This section aims at showing the differences between the oldline and the new CFW-08. The information below areaddressed to user that are used to line.

Table below shows the equivalence between the accessoriesof the old line an the new CFW-08.

AccessoriesWith the migration from the 16 bits microcontroller to theDSP of thenewCFW-08, the power supply of the electroniccircuits was changed from 5V to 3.3V. Consequently, theaccesories (keypads, communication modules, etc) of theold line CAN NOT BE USED with the new CFW-08 line.As general rule, use only accessories with WEG logo, asalready informed above.

Expansion of the Power RangeThe power range of the old line (0.25-2HP) has beenexpanded to (0.25 to 20)HP with the new CFW-08 line.

Control ModesOnly the CFW-08 line has:- Voltage Vector Control (VVC) that improves the inverter

performance considerably - adding theparameters P178,P399, P400, P402, P403, P404, P407, P408 and P409;

- The quadratic curve V/F improves the systema energysaving capability when loads with quadratic torque xspeed characteristics are driven, like pumps and fans.

Frequency ResolutionThe new CFW-08 has a frequency resolution 10 timeshigher than the oldline, i.e., it has a resoltion of 0.01Hz forfrequencies up to 100.0Hz and of 0.1Hz for frequencieshigher than 99.99Hz.

Switching Frequencies of 10kHz and 15kHzWhen the new CFW-08 is used, one can set the inverterswitching frequency to 10kHz and 15kHz, which enablesan extremly quiet operation.The audible noise level generated by the motor with 10 kHzis lower with the CFW-08, when compared with the line.This is due to the PWM modulation improvements of theCFW-08.

Inputs and Outputs (I/Os)The CFW-08 Plus line has more I/Os than the old line,while the CFW-08 is equivalent to theline in terms of I/Os.See table below:

(*) Two additional digital inputs are available when the digital inputs are used. (See

Parameter P235 and P239).

Table 2.2 – Number of digital inputs on the mline,on CFW08 and on the CFW08 Plus.

Parameters and Functions:

Parameters that are already used inline but have beenchangeda) P136 - Manual Torque Boost (IxR Compensation):

Besides the parameter name, also the way the userenters the IxR compensation value has been changed.In the old line, the parameter P136 had a family of 10curves (value range: 0 to 9). In the new CFW-08, the IxRCompensation is set by entering a percent (relating tothe input voltage) that defines the output voltage for anoutput frequency equal to zero. So larger curve set anda larger variation range is obtained.

Table below shows the equivalence between which wasprogrammed in the old line and which must beprogrammed in the new CFW-08 to obtain the sameresult.

But thecontrol connections (terminals XC1) differ betweenthe line and the CFW-08 line. Table below shows thesespin differences:

b) Automatic Torque Boost (Automatic IxR Compensation)and Slip Compensation:

In thelineonly the rated motor current (P401) was usedin the Automatic IxR Compensation and the SlipCompensation functions. In the line the rated motorpower factor of the motor was considered as a fixedvalue and equal to 0.9.Now in the new CFW-08, areused theparameters P401and P407 (rated motor power factor). Thus:

Example:When in an application with theline the following setting wasrequired: P401=3.8A, now with the new CFW-08 you mustperform the following setting:

P401=3.8A and P407=0.9 or

P407= rated cos of the used motor and P401=3.8 x 0.9P407

c) Quick Inputs:

In the new CFW-08, the response time of the the digitalinputs is 10ms (max.).In addition, the minimum acceleration and decelerationtime was reduced from 0.2s (line) to 0.1s (CFW-08).Besides the DC braking process can be interruptedbefore it has been concluded, for instance, when a newenabling is required.

d) Other changes:

P120=2 - digital reference backupviaP121 independentlyof the reference source.P265=14 - DI3: multispeed using ramp 2.

New Parameters and Functions:

The reference 1 of the multispeed that was in ParameterP121 (in line) is now in Parameter P124 (in CFW-08).

The DC link regulation level (ramp holding) can now beprogrammed in Parameter P151 - in theline this level wasfixed to 377V for the 200-240V line and 747V for the380-480V line.

Also the programming way of parameter P302 haschanged. In the line P302 was related to the voltageapplied to the output during the DC braking, now in the newCFW-08, P302 defines the DC Braking Current.

PID regulator.

Suammarizing, the new parameters are: P009, P040,P124, P151, P178, P202, P203, P205, P219, P238, P239,P240, P251, P252, P279, P399, P400, P402, P403, P404,P407, P408, P409, P520, P521, P522, P525, P526, P527,P528 and P536.

DANGER!Provide an AC disconnecting switch to switch OFF the inputpower to the inverter. This device shall disconnect the inverterfrom the AC input supply when required (e. g. duringmaintenance services).

ATTENTION!The AC input for the inverter must have a grounded neutralconductor.

NOTE!TheAC input must be compatible with the inverter rated voltage

Power Supply Line Capacity:

The CFW-08 is suitable to be used in circuits which cannot supplymore than30.000A rms symmetrically (240/480V).If theCFW-08 is installed in networks which can supply morethan 30.000Arms, you must provide suitable protectioncircuits such as fuses and circuit breakers.

3.2.4.3 GroundingConnections

DC Link Inductor / Line Reactors

The requirements for use of line reactors depend on severalapplication factors. Refer to Section 8.19.

NOTE!Capacitors for power factor correction are not required at theinput (L/L1, N/L2, L3 or R, S, T) and they must not be connectedat theoutput (U, V, W).

The inverter is provided with electronic protection againstmotor overload. This protection must be set according to thespecific motor. When the same inverter drives several motors,use individual overload relays for each motor. Maintain theelectrical continuity of the motor cable shield.

ATTENTION!If a disconnect switch or a contactor is inserted in the motorsupply line, do not operate them with motor running or wheninverter is enabled. Maintain the electrical continuity of themotor cable shield.

Dynamic Braking (DB)

When inverters with dynamic braking (DB) are used, the DBresistor shall be mounted externally. Figure 8.29 shows howto connect the braking resistor. Size it according to theapplication, not exceeding the maximum current of the brakingcircuit. For the connection between inverter and the brakingresistor, use twisted cable. Provide physical separationbetween this cable and the signal and control cables. Whenthe DB resistor is mounted inside the panel, consider wattloss generated when the enclosure size and requiredventilation are calculated.

DANGER!The inverter must be grounded to a protective earth for safetypurposes (PE).The earth or ground connection must comply with the localregulations. For grounding, use cables with cross sections asindicated in Table 3.4. Make the ground connection to agrounding bar or to the general grounding point (resistance10 ohms).

DANGER!Do not share the ground wiring with other equipment thatoperates with high currents (for instance: high voltage motors,welding machines, etc). If several inverters are used together,refer to Figure 3.7.

3.2.4.2 OutputConnections

48


ATTENTION!The AC input for the inverter must have a grounded neutralconductor.

EMI – Electromagnetic Interference

When electromagnetic interference (EMI), generated by theinverter, interferes in the performanceof other equipment, useshielded wires, or install the motor wires in metallic conduits.Connect one end of the shielding to the inverter groundingpoint and the other end to the motor frame.

Motor Frame

Ground always ground the motor frame. Ground the motor inthe panel where the inverter is installed or ground it to theinverter. The inverter output wiring must be laid separately fromthe input wiring as well as from the control and signal cables.

NOTE!Do not use neutral conductor for grounding purposes.

Inverter sideInsulate with tape

Figure 3.11 - Shield connection

Connect to earth: bolts are located on heatsink

Do not ground

During the signal and control wire installation note please thefollowing:

1) Cable cross section: (0.5 to 1.5)mm²/(20 to 14) AWG

2) Max. Torque: 0.50 N.m (4.50 lbf.in).

3) XC1 wiring must connected with shielded cables andinstalled separately at a distance of 10 cm each other forlengths up to 100m and at distance of 25cm each other forlengths over 100m. If the crossing of these cables isunavoidable, install them perpendicular, maintaining amimimum separation distance of 5 cm (2 in) at the crossingpoint.

Connect the shield as shown below:

4) For wiring distances longer than 50 m ( 150 ft), it's necessaryto use galvanic isolators for the XC1:5 to 9 analog signals.

5) Relays, contactors, solenoids or eletromagnetic brakingcoils installed near inverters can generate interferences inthe control circuit. To eliminate this interference, connectRC suppressor in parallel with the coils of AC relays.Connect free-wheeling diode in case of DC relays.

6) When external keypad (HMI) is used (refer to Chapter 8),separete the cable that connects the keypad to the inverterfrom other cables, maintaining aminimum distanceof 10cm(4 in) between them.

7) When analog reference (AI1 or AI2) is used and thefrequency oscillates (problem caused byeletromagnetic interference) XC1:5 connect to the in-verter heatsink.

NOTES!The inverter is factory default programmed with the digitalinputs as low level active (S1:1 in OFF). When the digitalinputs are used as high level active, you must set the jumperS1:1 to ON.The jumper S1:1 selects the HIGH level or LOW level activefor all 4 digital inputs. You can not select them separately.

3.2.6 Typical TerminalConnections

Connection 1 - Keypad Start/Stop (Local Mode)

With the factory default programming, you can operate theinverter in local mode with the minimum connections shownin Figure 3.6 (Power) and without control connections. Thisoperation mode is recommended for users who are operatingthe inverter for the first time. Note that there is no need ofconnection of control terminals.For start-up according to this operation mode, refer toChapter 5.

Connection 2 - Wire Start/Stop (Remote Mode)

Valid for factory default programming and inverter operatingin remote mode. For the factory default programming, theselection of the operation mode (local/remote) is made viathe key (default is local).The figure below shows the inverter terminal connection forthis type of driving.

3.3 European EMCDirective - Requirementsfor ConformingInstallations

The CFW-08 inverter series was designed considering safetyand EMC (ElectroMagnetic Compatibility) aspects.The CFW-08 units do not have an intrinsic function untilconnected with other components (e. g. a motor). Therefore,the basic product is not CE marked for compliance with theEMC Directive. The end user takes personal responsibilityfor the EMC compliance of the whole installation. However,when installed according to the recommendations describedin the product manual and including the recommended filtersand EMC measures the CFW-08 fulfill all requirements of theEMC Directive (89/336/EEC) as defined by the EMC ProductStandard for Adjustable Speed Electrical Power DriveSystems EN61800-3.Compliance of the CFW-08 series is based on the testing ofthe representative models. ATechnical Construction File waschecked and approved by a Competent Body.

Obs.: Single-phase input inverters use single-phase filters and only L1/L and L2/N are used.

The following items are required in order to have a conforminginstallation:

1) The motor cable must be armored, flexible armored orinstalled inside a metallic conduit or trunking with equivalentattenuation. Ground the screen/metallic conduit at both ends(inverter and motor).

2) Control (I/O) and signal wiring must be shielded or installedinside a metallic conduit or trunking with equivalentattenuation.

3.3.2 Emission and ImmunityLevels Description

3) The inverter and the external filter must be mounted on acommon metallic back plate with a positive electrical bondand in close proximity to one another. Ensure that a goodelectrical connection is made between the heatsink (inver-ter) / frame (external filter) and the back plate.

4) The length of the wiring between filter and inverter must bekept as short as possible.

5) The cable’s shielding must be solidly connected to thecommon back plate, using a metal bracket.

6) Grounding as recommended in this manual.

7) Use short and thick earthing cable to earth the external filteror inverter. When an external filter is used, only use an earthcable at filter input - the inverter earth connection is done bythe metallic back plate.

8) Earth the back plate using a braid, as short as possible. Flatconductors (e.g. braids or brackets) have lower impedanceat high frequencies.

9) Use cable glands whenever possible.

4.2.1 Keypad Operation All functions relating to the CFW-08 operation (Start/Stop,Direction of Rotation, JOG, Increment/Decrement of the Speed(Frequency) Reference, and selection of LOCAL/REMOTEmode) can be performed through theHMI selection. For factorydefault programming of the inverter, all keypad keys areenabled when the LOCAL Mode has been selected. Thesesame functions can be performed through digital and analoginputs. Thus you must program theparameters related to thesecorresponding inputs.

NOTE!The control keys , and are only enabled if:

P229=0 for LOCAL Mode operationP230=0 for REMOTE Mode operationThe key depends of the parameters above and if:P231=2

Keypad keys operation description:

When enabled (P220 = 2 or 3), selects the control input and thespeed reference (speed) source, toggling between LOCAL andREMOTE Mode.

When pressed, starts the motor according to accelerationramp up to the speed (frequency) reference. The function issimilar to that performed through digital input START/STOP,when it is closed (enabled) and maintained enabled.

Stop disables the inverter via deceleration Ramp.The Functionis similar to that performed through digital input START/STOP,when it is open (disabled) and maintained disabled.

When the JOG key is pressed, it accelerates the motoraccording to the acceleration ramp up to the JOG speedprogrammed in P122.This key is only enabled when the inverter digital inputs,programmed to general enable (if any) are closed.

When enabled (refer to the note above), reverses the motordirection of rotation.

Motor speed (frequency) setting: these keys are enabled forspeed setting only when:

the speed reference source is the keypad (P221 = 0 forLOCAL Mode and/or P222 = 0 for REMOTE Mode);the following parameter content is displayed: P002, P005or P121.

operation of the inverter (keys , , , and) and speed reference setting (keys and ).

Line voltage is too low for inverteroperation (undervoltage condition).

Inverter is READY to be started.

Inverter is in a Fault condition. Fault codeis flashing on the display. In our examplewe have the fault code E02 (refer tochaper Maintenance).

Inverter is applying a DC current on themotor (DC braking) according to thevalues programmed at P300, P301 andP302 (refer to Chapter 6).

Inverter is running self-tuning routine toidentify motor parameters automatically.This operation is controlled byP408(referto Chapter 6).

NOTE!The display also flashes in the following conditions, besidesthe fault conditions:

trying to change a parameter value when it is not allowed.inverter in overload condit ion (refer to ChapterMaintenance).

Parameters P002 toP099 are reserved for the display of read-only values. The factory default display when power is appliedto the inverter is P002 (frequency proportional value in V/Fcontrol mode and motor speed in rpm in vector control mode).Parameter P205 defines the initial monitoring parameter, i.e.,defines the read-only variable that will be displayed when theinverter is powered up. For further information refer to P205description in Chapter 6.

4.2.2 Inverter Status

Parameter P121 stores the speed reference set by these keys.

When pressed, it increases the speed (frequency) reference.

When pressed, it decreases the speed (frequency) reference.

Reference Backup:The last frequency reference set by the keys the and

is stored when inverter is stopped or the AC power isremoved, provided P120 = 1 (reference backup active is thefactorydefault). Tochange thefrequency referencebeforestartingthe inverter, the valueof theparameter P121, must be changed.

4.2.3 Read-Only Variables

72


NOTE!(1) For parameters that can be changed with themotor running,

the inverter will use the new value immediately after it hasbeen set. For parameters that can be changed only withmotor stopped, the inverter will use this new valueonly afterthe key is pressed.

(2) By pressing the key after the reprogramming, thenew programmed value will be stored automatically andwill remain stored until a new value is programmed.

4.2.4 Parameter Viewing andProgramming

All CFW-08 settings are made through parameters. Theparameter are shown on the display by the letter P followedby a number:Exmple (P101):

101 = Parameter Number

Each parameter is associated with a numerical value(parameter value), that corresponds to the selected optionamong the available ones for this parameter.

The parameter values define the inverter programming or thevalue of a variable (e.g.: current, frequency, voltage).For in-verter programming you should change the parametercontent(s).

It is necessary to set P000=5 before to change a parametervalue.Otherwise you can only read the parameter values, but notreprogram them. For more details, see P000 description inChapter 6.

5.1 PRE-POWERCHECKS

This Chapter provides the following information:

how to check and prepare the inverter before power-up;how to power-up and check for proper operation;how to operate the inverter when it is installed according tothe typical connections (refer to Section 3.2 - ElectricalInstallation).

The inverter shall be installed according to Chpater 3 -Installation and Connection. If the drive project is different fromthe typical suggested connections, follow the proceduresbelow.

DANGER!Alaways disconnect the AC input power before making anyconnections.

1) Check all connectionsCheck if the power, grounding and control connections arecorrect and well tightened.

2) Check the motorCheck all motor connections and verify if its voltage, currentand frequency match the inverter specifications.

3) Uncouple the load from the motorIf the motor can not be uncoupled, make sure that thedirection of rotation (FWD/REV) can not cause damage tothe machine.

After the inverter has been checked, AC power can be applied:

1) Check the power supplyMeasure the line voltage and check if it is within thespecified range (rated voltage: -15% / +10%).

2) Power-up the AC inputClose the input circuit breaker or disconnect switch.

3) Check if the power-up has been succesful - Inverterwith keypad (HMI-CFW08-P or HMI-CFW08-RS)

The keypad display will show:

CHAPTER 5 - START-UP

5.3 START-UP This Section describes start-up procedures when operatingvia the keypad (HMI). Two types of control will be considered:

V/F and Vetor Control:The V/F control is recommended in the following cases:

several motors driven by the same inverter;rated current of the motor is lower than 1/3 of rated invertercurrent;for test purposes, inverter is start-up without load.

The V/F control can also be used in applications that do notrequire fast dynamic responses, accurate speed regulationsor high starting torque (speed error will be a function of themotor slip); when you program parameter P138 - rated slip -you can obtain a speed accuracy of 1%.For the most applications, we recommend the vector controlmode, that permits a higher speed control accuracy (typical0.5%), higher starting torque and a faster dynamic response.

The necessary adjustments for the operation of the vectorcontrol areperformed automatically. In this case themotor shallbe connected to the CFW-08.

This means that the inverter is ready (rdy = ready) to beoperated.

- Inverter with dummy panel (TCL-CFW08 or TCR-CFW08).

The LEDs ON (green) and ERROR (red) are ON.Inverter runs some self-diagnosis routines. If no problems arefound the LED ERROR (red) turns OFF. This means that theinverter is now ready to be operated.

Thefour LEDs of thekeypad remains ON during this procedure.Inverter runs some self-diagnosis routines. If no problems arefound, the display shows:

DANGER!Even after theAC power supply has been disconnected, highvoltages may be still present. Wait at least 10 minutes afterpowering down to allow full discharge of the capacitors.

77


NOTE!The last frequency reference (speed) vale set via theand keys is saved.

If you wish tochange this value before inverter enabling, changeparameter P121 (Keypad Reference).

NOTES:(1) If the direction of rotationof themotor is not correct, switch off

the inverter. Wait at least for 10 minutes to allow completecapacitor discharge and then swap any two wires at the mo-tor output.

(2) If the acceleration current becomes too high, mainly at lowfrequencies, set thetorqueboost (IxR compensation) at P136.Increase/decrease the content of P136 gadually until youobtain an operation with constant current over the entirefrequency range.For thecaseabove, refer toParameter Description in Chapter6.

(3) If E01 fault occurs during deceleration, increase thedeceleration time at P101 / P103.

DETAILED PARAMETER DESCRIPTION

This chapter describes in detail all CFW-08 parameters andfunctions.

Please find below some symbols used in this chapter:AIx = Analog input number x.AO = Analog output.DIx = Digital input number x.F* = Frequency reference. This is the frequency value thatindicates the desired motor speed at the inverter output.F

e= Input frequency of theacceleration and deceleration ramp.

Fmax

= Maximum output frequency, defined at P134.F

min= Minimum output frequency, defined at P133.

Fs

= Output frequency - frequency applied to the motor.Inom = Rated inverter output current (rms), in Ampères (A). Thisvalue is defined in P295.Is

= Inverter output current.Ia

= Active current at inverter output, i.e., it is the compomentof the total motor current proportional to active electric powerabsorbed by the motor.RLx = Relay output number x.U

d= DC link voltage in the DC link circuit.

This section describes the main concepts related to theCFW-08 frequencyinverter.

As already informed in section 2.3, CFW-08 has in thesame product a V/F control and a sensorless vector control(VVC: “voltage vector control”).The user must choose one of them. Please find below adescription of each control mode.

This control mode is based on the constant V/F curve(P202=0- linear V/F curve). Its performance is limited at low frequenciesas function of the voltage drop in the stator resistance, thatcauses a significant magnetic flow reduction in the motor airgap and consequently reducing the motor torque. Thisdeficiency should be compensated by using manual andautomatic boost torque (IxR compensations), that are setmanually and depend on the user experience.

In most applications (for instance: centrifugal pumps and fans)the setting of these functions is enough to obtain the requiredperformance. But there are applications that require a moresophisticated control. In thesecases it´s recommended the useof the sensorless vector control, that will be described in thesection below.

6.2 INTRODUCTION

6.2.2 V/F Control

6.2.1 Control Modes

85

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

6.2.3 Vector Control (VVC)

In V/F control, the speed regulation, that can be obtained bysetting properly slip compensation can be maintained within1% to 2% of the rated speed. For instance, for a IV pole mo-tor/60Hz, the minimum speed variation at no load conditionand at rated load can be maintained between 18 and 36rpm.

There is still a variation of the linear V/F control: the quadraticV/F control. This control mode is suitable for applications likecentrifugal pumps and fans (loads with quadratic torque xspeed characteristics), since it enables a motor loss reduction,resulting in an additional energy saving by using an inverter.For more details about the V/F control mode, please refer tothe description of the parameters P136, P137, P138, P142and P145.

The CFW-08 vector control is sensorless, i.e., it does notrequire a signal of the speed feedback through tachogeneratoror encoder coupled on motor shaft.To maintain the magnetic flux in the motor air gap constant,and consequently the motor torque, within the whole speedvariation range (from zero up to the field weakening point), asophisticated control algorithm is used that considers themathematic model of the induction motor.Thus one can maintain the magnetic flux in the motor air gapapproximately constant at frequencies down to approximately1 Hz.In vector control mode one can obtain a speed regulation of0.5% (relating to the rated speed). Thus, for instance, for a IVpole motor/60Hz one can obtain a speed variation in the ran-ge of 10rpm (!).Other advantage of the vector control is its easy settingprocedure.The user needs only to enter in theparameters P399 and P407the information about the used motor (nameplate data) andruns the self-tuning routine(by setting P408=1) and the inverter configures itself to therequired application. So the inverter is ready to be operatedin an optimized manner.For more information, refer to the description of the followingparameters: P178 and P399 to P409.

86


The frequency reference (i.e., thedesired output frequency, oralternatively, themotor speed) can bedefined in several ways:

The keypad - digital reference that can be changed throughthe keypad (HMI), by using the keys and ,(see P221, P222 and P121);Analog input - the analog input AI1 (XC1:6) or the AI2(XC1:8) can be used, or both (see P221, P222 and P234to P240);Multispeed - up to 8 preset digital references (see P221,P222 and P124 to P131);Electronic potentiometer (EP) - another digital reference,its value is defined by using 2 digital inputs (DI3 and DI4) -see P221, P222, P265 and 266;Via serial.

Figure 6.1 shows through a diagram block the frequencyreference definition to be used by the inverter.

NOTE!AI2 is only available in CFW-08 Plus version.With S1:1 OFF and when connected to 24V(external) withS1:1 to ON.DIs ON when connected to 0V (XC1:5).When F*<0 one takes the module of F* and reverses thedirection of rotation (if this is possible - P231=2 and if theselected control is not forward run/reverse run.

6.2.5 Commands

6.2.6 Local/RemoteOperation Modes

The inverter has the following commands: PWM pulse enabling/disabling, definition of the direction of rotation and JOG.As the reference, the inverter commands can de defined inseveral ways.

The command sources are the following:

via keypad - keys , , and ;via control terminals (XC1) - digital inputs;via serial interface.

The inverter enabling and disabling commands can be definedas follows:

via keypad and of the HMI;via serial;start/stop (terminals XC1 - DI(s) - see P263 to P266);general enable (terminals XC1 - DI(s) - see P263 to P266);forward run (terminals XC1 - DI(s) - see P263 to P264), itdefines also the diretion of rotation;ON/OFF (3-wire controls) (terminals XC1 - DIs - see P263and P264).

The definition of the direction of rotation can be defined byusing:

the key of the keypad;serial;digital input (DI) programmed for FWD/REV (see P264 toP266);digital inputs programmed as FWD / REV, that defines bothinverter enabling or disabling and direction of rotation (seeP263 e P264);analog input - when the reference is via analog input and anegative offset is programmed (P236 or P240<0), thereference may assume negative values, thus reversing thedirection of the motor rotation.

User can define two different conditions relating to thefrequency reference source and the inverter commands: theseare the local and the remote operation modes.Figure 6.3 shows the local and remote operation modes in ablock diagram.With the factory setting in local mode the inverter can becontrolled by using the keypad, while in remote mode allcontrols are via terminals (XC1).

Parameter Unit Description / NotesTo operate JOG function works, the inverter must bedisabled by ramp (stopped motor). Thus if the controlsource is via terminal, there must be at least one digitalinput programmed as start/stop enabling (otherwise E24will be displayed), which must be OFF to enable the JOGfunction via digital input.The direction of rotation is defined by parameter P231.

Multispeed is used when the selection of anumber up to8 pre-programmed speeds is desired.It allows the control of the output speed by relating thevalues programmed by the parameters P124 to P131,according to the logical combination of the digital inputsprogrammed for multispeed.Activation of the multispeed function:- ensure that the reference source is given by themultispeed function, i.e., set P221=6 in local mode orP222=6 in remote mode;

- program one or more digital inputs to para multispeed,according to table below:

Defines the maximum and minimum output frequency(motor) when inverter is enabled.It is valid for any type of speed reference.The parameter P133 defines a dead zone when analoginputs are used - see parameters P234 to P240.P134 and thegain and offset of the analog input(s) (P234,P236, P238 and P240) define the scale and the rangeof the speed variation via analog input(s).

Compensates the voltage drop due to the motor statorresistance. It acts at low speeds by increasing the inver-ter output voltage, in order to maintain a constant torqueduring the V/F operation.The best setting is to program the lowest value for P136that still permits the motor start satisfactorily. If the valueis higher than required, an inverter overcurrent (E00 orE05) may occur due tohigh motor currents at low speeds.

This function compensates the drop of the motor speeddue to load, which is a inherent characteristic relating tothe operation principle of the induction motor.

This speed drop is compensated by increasing the outputfrequency (and voltage) (applied to the motor) as afunction of the increase of the active motor current, asshown in the block diagram and in the V/F curve below.

To set the parameter P138 use the following procedure:

- run the motor without load up to approximately half ofthe application top speed;

- measure the actual motor or equipment speed;- apply rated load to equipment;- increase parameter P138 until the speed reaches its

no-load speed.

Define the V/F curve used in V/Fcontrol (P202=0 or 1).These parameters allow changing the standard V/F cur-ve defined at P202 - programmable V/F curve.P142 sets the maximum output voltage. This value is setas a percent of the inverter supply voltage.Parameter P145 defines the rated frequency of the mo-tor used.The V/F curve relates the inverter output voltage andfrequency (applied to the motor) and consequently themagnetizing flux of the motor.The programmable V/F curve can be used in specialapplications where the motors used require a ratedvoltage and/or frequency different than the standardones. Examples: motor for 220V/400Hz and a motor for200V/60Hz.Parameter P142 is also useful in appplications thatrequire rated voltage different from the inverter supplyvoltage. Example: 440V line and 380V motor.

By this function an optimized deceleration t ime(minimum) is achieved for the driven load.This function is useful in applications with medium inertiathat require short deceleration times.In case of overvoltage trip during the decelearation, youmust reduce gradually the value of P151 or increase thetime of the deceleration ramp (P101 and/or P103).The motor will not stop if the line is permanently withovervoltage (U

d>P151). In this case, reduce the line

voltage, or increase the value of P151.If even with these settings the motor does not deceleratewithin the required time, you will have the followingalternatives- use the dynamic braking (for more details, see Item

8.21);- if inverter is being operated in V/F control, increase

P136;- if inverter is being operated in vector control, increase

P178.

But in some specific cases, differentvalues at P178 may be set.These conditions may be:- to increase the inverter torque capacity (P178>100%).Examples:1) to increase the motor starting torque and thus ensure

faster motor starts;2) to increase the inverter braking torque and thus allow

faster stops, without using dynamic braking.- to reduce the inverter energy consumption(P178<100%).

Parameter Unit Description / NotesDefines the inverter control mode. Item 5.3 gives someguidelines relating to the selection of control type.

P202 (3) 0 to 2Control Made [ 0 - V/F linear ]

-

As shown in table above, there are 2 V/F control modes:

Scalar Control Modes:Linear V/F control: this control mode ensures a flux in themotor air gap approximately constant from around 3Hzup to the field weakening (defined by the parametersP142 and P145).Thus in this speed range, an approximately constanttorque capacity is obtained. This control mode isrecommended for belt conveyors, extruding machines,etc.

Quadratic V/F control: in this control mode the flux in themotor air gap is proportional to the output frequency upto the field weakening point (defined at P142 and P145).Thus the torque capacity is a function of the quadraticspeed. The main advantage of this type of control is theenergy saving capability with variable torque loads, dueto the reduction of the motor losses (mainly due to motoriron losses and magnetic losses).

Main application fields for this type of control are:centrifugal pumps, fans, multimotor drivings.

The vector control allows a better performance regardingto torque and speed control. The CFW-08 vector controloperates without motor speed sensor (sensorless). Itmust be applied when followingperformances are required:- better dynamics (faster accelerations and stoppings);- when a more accurate speed control is required;- when high torques at low speeds are required ( 5Hz).Examples: in positioning, such as load moving, packingmachines, pumps, dosing machines, etc.The vector control can not be used in multimotorapplications.The performance of the vector control with a switchingfrequency of 10kHz is not so good as when a switchingfrequency of 5kHz or 2.5kHz is used. It is not possible touse a vector control with a switching frequency of 15kHz.For more details about the vector control, refer to Item6.2.3.

When the Al's are used as digitalinput whith logic NPN (P235 or P239 = 3) you must inserta 10Kresistor between the control terminals 7 and 6(for AI1) or 7 and 8 (for AI2).The inverter displays E24 when the signal AIx (P235 orP239) has been configured as digital input and AIx is atthe same time an analog reference (P221/P222).To use the bipolar option (-10 to +10)V with the version“A2” of the control board (refer to item 2.4) the followingsettings are needed:- P234 = 2 and P236 = -50 - using AI1- P234 = 2 and P240 = -50 - using AI2In the option 5 in P235 or P239, the AIx can detect anovertemperature fault (E32), through the motor PTCdetector. For this, the AIx must be configured to currentinput, i. e., the switch DIP S1:3 or SI:4 must be set toON. The figure below shows how to make the PTCconnection to the inverter:

Notes about the functions of the relay outputs:

1) When the definition in the function name is true, thedigital output will be activated, i.e., the relay coil isenergized.

2) When the option 'Not used' has been programmed,the relay output(s) will be disabled, i.e., the coil is notenergized.

3) CFW-08 Plus has 2 relay outputs (1 NO and 1 NCcontact). It is possible to emulate a reversal contactrelay by setting P277 = P279.

Definitions of the used symbols in the functions:- Fs = P005 - output frequency (motor)- Fe = reference frequency (ramp input frequency)- Fx = P288 - Fx frequency (user selected frequency

drive components temperature and thus reducing theiruseful life.The predominant frequency on the motor is twice theswitching frequency setat P297.Thus, P297=4 (5kHz) results in an audible motor noisecorresponding to 10kHz. This is due to the used PWMtechnique .The reduction of theswitching frequency also contributesto the reduction of instability and ressonance that mayoccur in certain application conditions, as well as reducesthe emission of electromagnetic energy by the inveter.The reduction of the switching frequencies also reducesthe leakage currents to ground, which may avoid thenuisance activation of the ground fault protection (E00).The option 15kHz (P297=7) is not available in vectorcontrol mode or when the external serial keypad (HMI-CFW-08-RS) is used.Use currents according to table below:

Before DC braking starts, there is a "Dead Time" (motorruns freely) required for the motor demagnetization. Thistime is function of the motor speed at which the DCbraking occurs.During the DC braking the LED display flashes

If the inverter is enabled during the braking process, thisprocess will be aborted and motor operates normally.DC braking can continue its braking process even afterthe motor has stopped. Pay special attention to thedimensioning of the motor thermal protection for cyclicbraking of short times.In applications where the motor current is lower than therated inverter current, and where the braking torque isnot enough for the braking condition, pleasecontact WEGto optimize the settings.

Parameter P311 sets the time required for the motorrestart, both for flying start function and the ride-throughfunction. Inother words, it defines the time to set the outputvoltage starting from 0V and up to reaching the ratedvoltage.

Operation of the flying start function:- It allows the motor to start when it is running. This

functions acts only when the inverter is enabled. Duringthe start, the inverter will impose the speed reference,creating a voltage ramp with time defined at P311.

- The motor can be started in conventional form, evenwhen the flying start has been selected (P310=1 or 2),adjusting one of the digital inputs (D13 or D14) to 13(flying start disable) and driving it (0V) during the mo-tor start.

Ride-Through operation:- Permits the inverter recovery, without disabling by E02

(undervoltage), when a momentary voltage drop in theline occurs.The inverter will be disabled only by E02, if the voltagedrop is longer than 2.0s.

- When the ride-through function is enabled (P310=2or 3) and if a voltage drop in the line occurs, so the linkcircuit voltage becomes lower than the permittedundervoltage level, the output pulses will be disabled(motor runs freely) and the inverter waits up to 2s forthe line re-establishment. If the line returns to is nor-mal status within this time, the inverter will enable againthe PWM pulses, imposing the frequency

6.3.5 Special Function Parameters - P500 to P599

6.3.5.1 PID Introduction CFW-08 is fitted with the PID regulator that can beused forclosed loop process control. This function acts as aproportional, integral andderivative regulator,superimposed on the normal inverter speed control.

The speed will be changed in order to maintain the processvariable (the variable that should be controlled - for instance:water level of a container) at the desired value, set in thesetpoint.

This regulator can, for instance, control the flow in a pipingsystem.

The setpoint (flow) can be given by the analog input AI2 orthrough P525 (digital setpoint), and the flow feedbacksignal is given at analog input AI1.

Other application examples: level control, temperaturecontrol, dosing control, etc.

Figure 6.26 shows the block diagram of the PID regulator.

The feedback signal must be sent to the analog input AI1.The setpoint is the value of the process variable at whichthe operation is desired. This value is entered as apercentage and is defined by the following equation:

6.3.5.2 Description

where both the setpoint and the full scalevalue of the sensorare given by the process unit (°C, bar, etc.).Example: a pressure transducer (sensor) with ouput 4 -20mA and full scale of 25bar (i.e., 4mA=0bar and20mA=25bar) and P234=2.00. If the control of 10bar isdesired, you should enter the following setpoint:

setpoint (%) = 10 x 2 x 100% = 80%25

The setpoint can be defined via:- Keypad: digital setpoint, parameter P525.- Analog input AI2 (only available in the CFW-08 Plus):

the percentage value is determined by consideringP238, P239 and P240 (see description of theseparameters).

131


The parameter P040 indicates the value of the processvariable (feedback) in the scale selected at P528, that isset according to the following equation:

Example: Consider the data of the example above(pressure sensor of 0-25bar and P234=2.00) . P528 mustbe set to 25/2=12.5.

The parameter P040 can be selected as the display defaultparameter P205=6.

P528 = full scale value of the used sensorP234

6.3.5.3 PID Start-Up Guide Please find below astart-up procedure for thePID regulator:

Initial Definition1) Process - Definition of the PID action type that the

process requires: direct or reverse. The control actionmust be direct (P527=0) when it is required to increasethe motor speed and so also increment the processvariable. Otherwise select reverse (P527=1).Examples:a) Direct: pump driven by inverter and filling a tank

where the PID regulates the tank level. To increasethe level height (process variable) the flow must beincreased and consequently also the motor speedmust be increased.

b) Reverse: fan driven by an inverter to cool a coolingtower, with the PID controlling the temperature of thistower. When it is required to increase the towertemperature (process variable), the cooling powermust be descreased by reducing the motor speed.

NOTE!When the PID function (P203=1) is set:

The digital input DI3 is automatically set to manual/automatic (P265=15). Thus when DI3 is open, the manualmode is activated and when DI3 is closed, thePID regulatorstarts to operate (closed loop control - automatic mode).If the function of this digital input (DI3) is changed, theoperation of the inverter will be always in manual mode.If P221 or P222 is equal to 1, 4, 5, 6, 7 or 8 the E24 errormesage will be displayed. Set P221 and P222 equal to 0or 2 according to the requirement.The JOG and the FWD/REV functions are disabled. Theinveter enabling and disabling commands are defined byP229 and P230.In the manual mode, the frequency reference is given byF*, as shown in figure 6.1.When the operation mode is changed from manual toautomatic, P525 is automatically set to the value of P040(at the instant immediately before the commutation). Thuswhen the setpoint is defined by P525 (P221 or P222=0),the changing from manual to automatic is smooth [there´snot occur abrupt oscillation in the frequency (speed)reference].The analog output can be programmed to indicate theprocess variable (P040) or the PID setpoint with P251=6or 4, respectively.Figure 6.27 shows an application example of an invertercontrolling a process in closed loop (PID regulator).

134


2) Feedback (process variable measurement):The feeback is always realized via analog input AI1.

Transducer (sensor) to be used for the feedback of thecontrol variable: it is recommended to use a sensor withfull scale with at least 1.1 times higher than the largestvalue of the process variable that shall be controlled.Example: If a pressure control at 20bar is desired, selecta sensor with a control capacity of at least 22bar.

Signal type: set P235 and the position of the switch S1on the control board according to the transducer signal(4 -20mA, 0 -20mA or 0 -10V).Set P234 and P236 according to the variation range ofthe used feedback signal (for more details, seedescription of the parameters P234 to P240).

Example: suppose the following application:- full scale of the transducer (maximum value at the

transducer output) = 25bar (FS=25);- operation range (range of interest) = 0 to 15bar

(FO=15).

Considering a safety margin of 10%, the measuring ran-ge of the process variable must be set to: 0 a 16.5bar.Thus: FM=1.1xFS=16.5.Parameter P234 must be set to:

P234 = FS = 25 = 1.52FM 16.5

As the operation range starts at zero, P236=0, thus asetpoint of 100% represents 16.5bar, i.e., the operationrange, in percentage, is within: 0 to 90.9%.

NOTE!In the most cases it is not necessary to set the gain and theoffset (P234=1.00 and P236=0.0). Thus the percentage valueof the setpoint is equivalent to the percentage value of the fullscale of the used sensor. However if the maximum resolutionof the analog input AI1 (feedback) is desired, set P234 andP238 according to comments above.

Setting of the display indication to the process variablemeasuring unit (P040): set P528 according to the full scaleof the used transducer (sensor) and defined P234 (seedescription of parameter P528 below).

135


3) Reference (setpoint):Local/remote mode.Referencesource: set P221 or P222 according to definitonabove.

4) Speed limits: set P133 and P134 according to theapplication.

5) Indication:Display (P040): P040 can be the display default parameterby setting P205=6.Analog output (AO): it is possible to indicate the processvariable (feedback) or the setpoint of the PID regulator atthe analog output by setting P251 to 6 or 9, respectively.

Start-up1) Manual operation (DI3 open):

Display indication (P040): check indication based onexternal measurement and on the feedback signal(transducer) at AI1.Indication of the process variable at the analog output (AO),if P251=6.Set the frequency reference (F*) until the desired value ofthe process variable is reached.Only then switch to the automatic mode (inverter will setautomatically P525=P040) if P536 = 0.

2) Automatic operation: close DI3 and make the dynamicsetting of the PID regulator, i.e., adjust the proportional gain(P520), integral gain (P521) and differential gain (P522).

NOTE!The inverter setting must be correct in order to obtain a goodperformanceof thePID regualtor. Ensure the following settings:

Torque boosts (P136 and P137) and slip compensation(P138) in the V/F control (P202=0 ou 1);

Ensure that the self-tuning has been run, if in vector control(P202=2);

Acceleration and deceleration ramps (P100 to P103);

Current limitation (P169).

DIAGNOSTICSAND TROUBLESHOOTING

This chapter assists the user to identify and correct possiblefaults that can occur during the CFW-08 operation. Alsoinstructions about required periodical inspections and cleaningprocedures are also provided.

When a fault is detected, the inverter is disabled and the faultcode is displayed on the readout in EXX form, where XX isthe actual fault code.

To restart the inverter after a fault has occurred, the invertermust be reset. The reset can be made as follows:

disconnecting and reapplying the AC power (power-onreset);by pressing the key (manual reset);automatic reset through P206 (auto-reset);via digital input: DI3 (P265=10) or DI4 (P266=10),DI5 (P267=10) or DI6 (P268=10).

The table below defines each fault code, explains how to resetthe fault and shows the possible causes for each fault code.

NOTE!The fault E22, E23, E25, E26, E27 and E28 are related to theserial communication and are described in Item 8.22.5.4.

FAULT RESET (1) POSSIBLE CAUSES

141


NOTE!Long motor cables (longer than 50m (150ft)) can generateexcessive capacitance to ground. This can cause nuisanceground fault trip and consequently disabling by E00 faultimmediately after the inverter has been enabled. Solution:

Reduce the switching frequency (P297).Connect a load reactor in series with the motor supply line.Refer to Section 8.20.

NOTE!The faults act as follows:

E00 to E06: switches off the relay that has beenprogrammed to “no fault”, disables the PWM pulses,displays the fault code on the display and the “ERROR”LED flashes.Some data are saved on the EEPROM memory: keypadreference and EP (electronic potentiometer) (when thefunction “backup of the references” at P120 has beenenabled), the occurred fault number, the status of theintegrator of the IxT function (overcurrent).

8.18 RFI FILTER The installation of frequency inverters requires some care inorder to prevent electromagnetic interferences (EMI).This electromagnetic interference may disturb the operationof the inverter itself or other devices, such as electronicsensors, PLCs, transducers, radio equipment, etc. installedin the proximity.To avoid these troubles, follow the installation instructionscontained in this Manual.In this case, avoid the installation of electromagnetic noisegenerating circuits, such as power cables, motors, etc. nearto signal or control cables.Care should also be taken with the radiated interference, byshielding the cables and the circuits that tend to emitelectromagnetic waves and can cause interference.The electromagnetic interference can also be transmittedthrough power supply line. This type of interference isminimized in the most cases by capacitive filters which arealready installed inside the CFW-08.However, when inverters are installed in residential areas, theinstallation of additional filter may be required.These filters may be installed internally (on some types) orexternally.As defined in standards, theClass B filter has more attenuationcapacity than the Class A filter , thus being more suitable forresidential areas.Section 8.1 lists the available RFI filters with the respectiveinverter models.The inverters with internal ClassA filters have thesame externaldimensions as the inverters without filter.Theexternal Class B filters must be installed between thepowersupply lineand the inverter input, as shown in figure8.26 below.Instructions for the RFI filter installation:

Install the inverter and the filter on a metallic groundedplate as near to each other as possible and ensure agood electrical contact between the grounded plate andthe inverter and filter frames.For motor connection use a shielded cable or individualcables inside a grounded metallic conduit.

NOTE!For installations that must meet the European standards referto item 3.3.

8.19 LINE REACTOR Due to the input circuit characteristic, common to the mostinverters available on the market, consisting of a diode rectifierand a capacitor bank, the input current (drained from the powersupply line) of inverters is a non sinusoidal waveform andcontains harmonics of the fundamental frequency (frequencyof the power supply - 60Hz or 50Hz).These harmonic currents circulate through the power supplyline and cause harmonic voltage drops which distort the powersupply voltage of the inverter and other loads connected tothis line. These harmonic currents and voltage distortions mayincrease the electrical losses in the installation, overheatingthe components (cables, transformers, capacitor banks,motors, etc.), as well as lowering the power factor.Theharmonic input currents depend on the impedance valuesthat are present in the rectifier input/output circuit.The installation of a line reactor reduces theharmonic contentof the input current, providing the following advantages:

increasing the input power factor;reduction of the RMS input current;reduction of the power supply voltage distortion;increasing the life of the DC link capacitors.reduction of the overvoltage transients that may occur inthe power supply line.

8.19.1 Application Criteria In a general manner, the CFW-08 series inverters can beconnected directly to thepower supply line without line reactors.But in this case, ensure the following:

To ensure the inverter expected life, a minimum lineimpedance that introduces avoltage drop as shown in table8.3, as a function of the motor load, is recommended. If theline impedance (transformers + wirings) is lower than thesevalues, it is recommended to use line reactor(s).When it is necessary to add a line reactor to the system, itis recommended to size it considering a 2% to 4% voltagedrop (for nominal output current). This pratice is results in acompromise between motor voltage drop, power factorimprovement and harmonic current distortion reduction.This practice results in a compromise between motorvoltage drop, power factor improvement and harmoniccurrent distortion reduction.Always add a line reactor, when capacitors for power factorcorrection are installed in the same line and near to theinverter.Figure 8.27 shows the line reactor connection to the input.Use the following equation to calculate the value of the linereactor necessary to obtain the desired percentage of thevoltage drop:

Note: The value for the rated apparent power can be obtained in section 9.1 of thismanual.

The use of a three-phase load reactor, with an approximate2% voltage drop, adds an inductance at the inverter PWMoutput to the motor. This decreases the dV/dt (voltage risingrate) of the pulses generated at the inverter output. Thispractice reduces the voltage spikes on the motor windingsand the leakage currents that may be generated when longcables between inverter and motor (as a function of the"transmission line" effect) are used.There are many factors that influence the peak level (Vp) andthe rise time (tr) of voltage spikes: cable type, cable length,motor size, switching frequency and so on.WEG recommends using a load reactor when the supplyvoltage is higher than 500V, though this is not always required.WEG, as a specialist in both motors and inverters (VSDs) isable to provide an integrated solution.The load reactor value is calculated in the same way as theline reactor (see item 8.19.1).If the cables between inverter and motor are longer that 100m(300ft), the cable capacitance to ground may cause nuisanceovercurrent (E00) trips. In this case it is also recommended touse a load reactor.

8.21 DYNAMIC BRAKING The dynamic braking is used where short deceleration timesare required or where high inertia is present.For the correct sizing of the braking resistor, application datasuch as, deceleration time, load inertia, braking duty cyclemust be considered.In any case, the rms current capacity and the maximum peakcurrent must be considered.The maximum peak current defines the minimum permittedohmic value for the braking resistor. Refer to table 8.5.The DC link voltage level for the actuation of the dynamicbraking is as follows:

PE PER S T U V W UVW

8.21.1 Resistor Sizing The braking torque, that can beobtained through the frequencyinverter, without using the dynamic braking module, varies from10% to 35% of the rated motor torque. During the decelerationprocess, the kinetic energy of the load is regenerated into theinverter DC link. This energy loads up the capacitors byincreasing the DC link voltage. When this energy is not fullydissipated, it may generate a DC link overvoltage trip (E01)and disabling the inverter.To obtain higher braking torques, the use of dynamic brakingis recommended where the excess of the regenerated energyis dissipated in a resistor mounted externally to the inverter.The braking resistor is defined according to the decelerationtime, load inertia and resistive torque.In most cases, a resistor with an ohmic value as indicated onthe table below and a power rating of 20% of the driven motorcan be used.Use wire type or tape type resistors with suitable insulation towithstand the instantaneous current peaks.

corresponds to the sum of the braking times duringthe most severe 5 minute cycle.

8.21.2 Installation Connect the braking resistor between the +UD and BRpower terminals (refer to section 3.2.1).Make this connection with a twisted pair. Run this cableseparately from any signal or control wire. Size the cablecross section according to the application, by consideringthe maximum and the rms current.If the braking resistor is installed inside the inverter panel,consider the heat dissipated by the resistor when definingthe panel ventilation.

For critical applications with very short braking times, highinertia loads (ex.: centrifuges) or with very short and frequentduty cycles, contact WEG to define the most suitable resistor.

DANGER!The internal inverter braking circuit and the braking resistorcan be damaged when not correctly sized or when the linevoltage exceeds the maximum allowed value.In this case, the only guaranteed method to avoid burning thebraking resistor and eliminate risk of fire is the installation of athermal overload relay in series connected with the resistorand/or the installation of a thermostat on the resistor body,wiring it in such a way that it disconnects the inverter powersupply in case of overheating, as shown in figure 8.29:

Typical examples of network use:PC (master) for the parametrization of one or severalinverters at the same time;SDCD monitoring inverter variables;PLC controlling the operation of one or more inverters in aindustrial process.

The physical connection between the inverters and the masteris performed according to one of the standards below:a. RS-232 (point-to-point up to 10m);b. RS-485 (multipoint, galavanic isolation, up to 1000m);.

8.22.2 Interfaces Description

The inverters have a control software for data transmission/reception through serial interface, thus facilitating the receptionof data that have been sent by the master and the transmissionof the data requested by the master.This softwaresupports WEG protocoland ninedifferent Modbus-RTU modes, that can be selected via parameter P312. Thesubjects broached in this Section refers to WEG protocol. Formore details about the Modbus-RTU, see item 8.23.The transfer rate is 9600 bits/s, following an exchange protocolof question/answer typeby usingASCII characters.The master is able to realize the following operations related toeach inverter:

This interface permits the linkage of up to 30 inverters to amaster (PC, PLC, etc.), attributing and setting for each inver-ter an address (1 to 30). In addition to these 30 addresses,there are two addresses to perform special tasks:

Address 0: any inverter in the network is inquired,independently of its address. Only one inverter can beconnected to the network (point-to-point) in order to preventshort-circuits in the line interface.Address 31: a control can be transmitted to all inverters inthenetwork simultaneously, without acceptance recognition.List of addresses and corresponding ASCIIcharacters.

8.22.2.1 RS-485

Table 8.6 - Adresses and corresponding ASCII characters list

172


The connection between the network participants is performedthrough a pair of wires. The signal levels are according to theEIA RS-485 STANDARD with differential receivers andtransmitters. You must use the serial communication moduleKRS-485-CFW-08 (refer to section 8.11).When themaster is fitted only with aRS-232 serial interface, youmust apply a level conversion module from RS-232 to RS-485.

In this case we have the connection of a master to an inverter(point-to-point). The data can be exchanged in a bi-directionalway, but not simultaneously (HALF DUPLEX).The logical levels meet the EIA RS-232C STANDARD, thatspecifies the use of balanced signals. In this case one wire isused for the transmission (TX), onewire for the reception (RX)and one wire for the return (0V).This configuration is a threewire economy model.You must use theRS-232 (KCS-CFW08) module in the inver-ter (refer to Section 8.9).

The tems of this Section describe the protocol used in theserial communication.

Parameters: are those existing in the inverters whosevisualization or alteration is possible through the keypad(HMI) interface.Variables: are values that have specific inverter functionsand that can be read and, in some cases, modified by themaster.

8.23 MODBUS-RTU

8.23.1 Introduction toModbus-RTU Protocol

Modbus protocol has been already developed 1979 firstly.Currently it is a wide diffused open protocol, used by severalmanufacturers in different equipment. The Modbus-RTUcommunication of the do CFW-08 has been developed byconsidering two documents:

1. MODBUS Protocol Reference Guide Rev. J, MODICON,June 1996.

2. MODBUS Applicat ion Protocol Specification,MODBUS.ORG,may 8th 2002.

In these documents are defined the format of the messagesused by these elements that are part of the Modbus network,the services (or functions) that can be made available vianetwork, and also how these elements exchange the data onthe network.

8.23.1.1 TransmissionModes

8.23.1.2 Message Structure inRTU Mode

The Modbus RTU network operates in Master-Slave systemand it can consist of up to 247 slaves but only one Master. Themaster always initiates the communication with a question toa slave and the slave answers the question. Both messages(question and answer) have the same structure: Address,Function Code, and CRC. Depending on what is beingrequested, only the data field has variable length.

Two transmission modes are defined in the protocol definition:ASCII and RTU. The transmission modes define the form howthe message bytes are transmitted. It is not permitted to usethe two transmission modes on the same network.In the RTU modeeach transmitted word has one start bit, eightdata bits, 1 parity bit (optional) and 1 stop bit (2 stop bits, if noparity bit is used). Thus the bit sequence for the transmissionof 1 byte is as follows:

Figure 8.32 - Message Structure

Start B0 B1 B2 B3 B4 B5 B6 B7 Parity or Stop Stop

185


Address:The master initiates the communication by sending one bytewith the address of the slave to which the message isaddressed. The slave with the right slave address initiatesthe message with its own address. The master can also senda message destined to address 0 (zero), which means thatthe message is destined to all network slaves (broadcast). Inthis case no slave will answer to the master.

Function Code:This field contains an only byte, where the master specifiesthe type of service or the function requested to theslave (read,write, etc.). According to the protocol, each function is used toaccess a specific data type. In the CFW-08 all data areavailable as holding type registers (referenced from theaddress 40000 or’ 4x’). Besides these registers, the inverterstatus (enabled/disabled, with error/noerror and the commandfor the inverter (run/stop, run CW/CCW, etc.) can be alsoaccessed through the coils read/write functions or the internalbits (referenced from the address 00000 or ‘0x’ on).

Data Field:This field has variable length. The format and the content ofthis field depend on the used function and transmitted values.This field and the respective functions are described in item8.23.3.

CRC:The last part of the message is the field for checking thetransmission errors. Theused method is theCRC-16 (CyclingRedundancy Check). This field is formed by two bytes, wherethe least significant byte (CRC-) is transmitted first and onlythen the most significant byte is transmitted (CRC+).CRC calculation is started by loading a 16-bit variable(mentioned from now on as CRC variable) with FFFFh value.Then following steps are executed with the following routine:

1. The first message byte (only the data bits - the start bit,parity bit and stop bit are not used) is submitted to the XORlogic (OR exclusive) with the 8 least significant bits of theCRC variable, returning the result to the CRC variable,

2. Then the CRC variable is displaced oneposition to the right,in the direction of the least significant bit and the positionof the most significant bit is filled out with zero 0 (zero).

3. After this displacement, the flag bit (bit that has beendisplaced out the CRC variable) is analyzed, by consideringthe following:

If the bit value is 0 (zero), no change is made.If the bit value is 1, the CRC variable content is submittedto XOR logic with a constant A001h value and the valueis returned to the CRC variable.

186

T11 bits = Time to transmit one word of the message.Tentre bytes = Timebetween bytes (can not be longer than T3,5x).T3,5x = Minimum interval to indicate the begin and the

4. Repeat steps 2 and 3 until the eight displacements havebeen realized.

5. Repeat the steps 1 to 4, by using the next byte messageuntil the whole message have been processed. The endcontent of the CRC variable is the value of the CRC fieldthat is transmitted at the end of the message. The leastsignificant part is transmitted first (CRC), only then the mostsignificant part (CRC+) is transmitted.

Times between Messages:In the RTU mode there is no specific character that indicatesthe beginning or theend of a message. Thus theonly indicationfor the beginning or the end of a new message is the datatransmission absence in the network by 3.5 times the timerequired for transmission of one data word (11 bits). Thus if amessage is initiated after elapsing of the minimum timerequired without transmission, the network elements assumethat the received character represents the beginning of a newmessage. In similar mode, after this time has elapsed, thenetwork elements will assume that the message has beenended.

If during the transmission of a message, the time betweenthe bytes is longer than this minimum required time, themessage will be considered invalid, since the inverter willdiscard the already received bytes and will mount a newmessage with the bytes that are being transmitted.The table below shows the time for three dif ferentcommunication rates.

8.23.2.2 InverterConfiguration inthe Modbus-RTUNetwork

8.23.2 Operation of theCFW-08 in theModbus-RTUNetwork

The CFW-08 frequency inverters operate as slaves of theModbus-RTU network. The communication initiates with themaster of the Modbus-RTU network requesting a service for anetwork address. When the inverter is configured to thecorresponding address, it processes the question andanswers to the master as requested.

8.23.2.1 InterfaceDescription

The CFW-08 frequency inverters use a serial interface for thecommunication with the Modbus-RTU network. There are twoways to perform the connection between the network masterand the CFW-08:

RS-232:The interface is used for the point-to-point connection(between a single slave and the master).Max. distance: 10 meters.Signal levels according to EIA STANDARD RS-232C.Three wires: transmission (TX), reception (RX) and return(0V).The RS-232 module (KCS-CFW08) must be used (seeitem 8.9).

RS-485:This interface is used for multipoint connection (severalslaves and the master).Max. distance: 1000 meters (use of shielded cables).Signal levels according to EIA STANDARD RS-485.Must be used with the module RS-485 (KRS-485-CFW08- see item 8.11).

Note: For connection, see 8.22.7.

To ensure a correct communication in the network, you mustconfigure the inverter address in the network as well as thetransfer rate and the existing parity type, besides the correctphysical connection.

Inverter Address in the Network:The inverter address is defined through theparameter P308.If the serial communication type (P312) has been configuredto Modbus- RTU, you may select the addresses from 1 to247.Each slave shall have a different address.The master does not have address.The slave address must be known, even when connectionis made point-to-point.

188


8.23.2.3 Access to theInverter Data

All parameters and available basic variables for the CFW-08can be accessed through the network:

Parameters: are those set in the inverter and that can bedisplayed and changed through the HMI (Human-MachineInterface) (see item 1 - Parameters).Basic Variables: are the internal inverter variables that canbe accessed only through serial interface. For instance,trough these basic variables you can change the speedreference, read the inverter status, enable or disable theinverter, etc. (see item 8.22.5.1 - Basic Variables).Register: nomenclature used to represent both parametersand basic variables during data transfer.Internal Bits: bits that are accessed only through the serialinterface and that are used for inverter status controllingand monitoring.

Item 8.22.3.2 defines the resolution of the parameters andvariables transmitted via serial interface.

Available Functions and Response Times:In the Modbus RTU protocol specification is defined thefunctions used for accessing different types of registersdescribed in thespecification. In the CFW-08 both parametersand basic variables aredefined as being holding type registers(referenced as 4x). In addition to these registers, it is alsopossible to access the internal controlling and monitoring bitsdirectly (referenced as 0x).Following services (or functions) are available in the CFW-08frequency inverter for accessing these registers:

Read CoilsDescription: reading of internal register blocks or coils.Function code: 01.Broadcast: not supportedResponse time: 10 to 20 ms.

Read Holding RegistersDescription: reading of register blocks of holding type.Function code: 03.Broadcast: not supportedResponse time: 10 to 20 ms.

Write Single CoilDescription: writing in a single internal bit or coil.Function code: 05.Broadcast: supported.Response time: 10 to 20 ms.

Transmission Rate and Parity:Both configurations are defined by parameter P312.

Baud rates: 9600, 19200 or 38400 bits/s.Parity: None, odd parity, even parity.All slaves and even the network master must use the samebaud rate and parity.

NOTE!TheModbus RTU network slaves are addressed from 1 to247.Master uses address 0 to send messages that are commonto all slaves (broadcast)

Data Addressing and Offset:The CFW-08 data addressing is realized with an offset equalto zero that means that the address number is equal to theregister number. The parameters are available from address0 (zero) on, whilst the basic variables are available fromaddress 5000 on. In same way, the status bits are madeavailable from address 0 (zero) on and the control bits aremade available from address 100 on.Table below shows the addressing of bits, parameters andbasic variables:

190


NOTE!All registers (parameters and basic variables) are consideredas holding type registers, referenced from 40000 or 4x, whilstthe bits are referenced from 0000 or 0x.The status bits have the same functions of the bits 8 to 15 ofthe logic status (basic variable 2). These bits are availableonly for read, thus any attempt towrite command returns errorstatus to the master.

8.23.3 Detailed FunctionDescription

This section describes in details the functions that areavailable in the CFW-08 for the Modbus RTU communication.Please note the following during the message preparation:

Values are always transmitted as hexadecimal values.The address of one data, the data number and the value ofthe registers are always represented through 16 bits. Thusthese fields are transmitted by using two bytes (high andlow). To access the bits, and the form to represent one bitdepend on the used function.The messages, both for enquiry and response, cannot belonger than 128 bytes.The resolution of each parameter or basic variable is asdescribed in item 8.22.3.2.

8.23.3.1 Function 01 -Read Coils

It reads the content of an internal group of bits that mustcompulsorily in a numerical sequence. This function has thefollowing structure for the read and response messages (thevalues are always hexadecimal, and each filed represents onebyte):

Table 8.16 - Command bits signified

Table 8.17 - Function 01structure

The command bits are available to read and write and theyhave the samefunction of the logic command bits 0 to7 (basicvariable 3), however no requiring the use of the mask. Thebasic variable 3 write influences the status of these bits.

192


Each response bit is placed at a position of the data bytessent by the slave. The first byte, from the bits 0 to 7, receivesthe first 8 bits from the initial address indicated by the master.The other bytes (if the number of the read bits is higher than8) remain in the same sequence. If the number of the readbits is not a multiple of 8, the remaining bits of the last byteshould be filled out with 0 (zero).

Example: reading of the status bits for general enable (bit1) and direction of rotation (bit 2) of then CFW-08 at theaddress 1:

8.23.3.2 Function 03 -Read HoldingRegister

It reads the content of a group of registers that must becompulsorily in a numerical sequence. This function hasfollowing structure for the read and response messages (thevalues are always hexadecimal values, and each fieldrepresents one byte):

As the number of read bits in the example is smaller than 8,the slave required only 1 byte for the response. The value ofthe byte was 02h,That as binary value will have the form 0000 0010. As thenumber of read bits is equal to 2, only the two less significantbits, that have the value 0 = general disable and 1 = directionof rotation are of interest, are of interest. The other bits, asthey did not be requested, are filled out with 0 (zero).

8.23.3.3 Function 05 -Write Single Coil

This function is used to write a value to a single bit. The bitvalue is represented by using two bytes, where FF00hrepresents the bit that is equal to 1, and 0000h represents thebit that is equal to 0 (zero). It has the following structure (thevalues are always hexadecimal, and each field represents onebyte):

Example: Read of the value proportional to the frequencyvalue (P002) and motor current (P003) of the CFW-08 ataddress 1:

P003 (high) 02hP003 (low) 8Ah

CRC- 38hCRC+ 95h

Each register is always formed by two bytes (high e low). Forthe example, we have P002 = 09C4h, that in decimal numberis equal to 2500.As this parameter have a decimal place indication, the realread value is 25.00Hz. In the same way we will have a currentvalue P003 = 028Ah, that is equal to a 650 decimal. As thecurrent has two decimal resolution, the read value is 6.50 A.

8.23.3.5 Function 15 -Write MultipleCoils

This function allows writing values for a bit group that must bein numerical sequence. This function can be also used to writea single bit (the values are always hexadecimal, and eachfield represents one byte).

8.23.3.4 Function 06 -Write SingleRegister

This function is used to write a value to a single register. Thisfunction has following structure (values are alwayshexadecimal values, and each field represents one byte):

CRC- 4BhCRC+ E7h



Register (high) 13hRegister (low) 8ChValue (high) 0BhValue (low) B8h

CRC- 4BhCRC+ E7h

For this function, the slave response will be again a copyidentical to the request made by the master. As alreadyinformed above, the basic variables are addressed from 5000,thus the basic variable 4 will be addressed at 5004 (138Ch).The value for this variable is 30.00Hz, that is represented by3000 (0BB8h).

For this function, the slave response is an identical copy ofthe query sent by the master.



195


The value of each bit that is being sent is placed at a positionof the data bytes sent by the master. The first byte, in the bits0 to7, receives the 8 first bits by starting from the initial addressindicated by the master. The other bytes (if the number ofinscribed bits is higher than 8) remain in sequence. If thenumber of inscribed bits is not a multiple of 8, the remainingbits of the last byte should be filled in with 0 (zero).

Example: command writing for general enabling (bit 100 =1), general enabling (bit 101 = 1) and CWW-direction ofrotation (bit 102 = 0), for a CFW-08 at address 1:

8.23.3.6 Function 16 -Write MultipleRegisters

This function allows writing values to a register group that mustbe in numerical sequence. This function can also be used towrite a single register (the values are always hexadecimalvalues and each field represents one byte).

As only three bits are written, the master needed only onebyte to transmit the data. The transmitted values are in thethree less significant bits of the byte that contains the valuefor the bits. The other bits of this byte remained with the value0 (zero).

ter firmware version, in ‘VX.XX’ format.The read code indicates which information categories arebeing read and if the objects are accessed individually ofby sequence.In the example, the inverter supports 01 (basic informationin sequence), and 04 (individual access to the objects).The other fields for the CFW-08 have fixed values.Example: read o basic information in sequence, startingfrom object 00, of a CFW-08 at address 1:


198


In the example the Object Value has not been represented ashexadecimal value, but with corresponding ASCII characters.For instance, for the object 00, the ´WEG‘ value has beentransmitted as being three ASCII characters, that ashexadecimal have the values 57h (W), 45h (E) and 47h (G).

8.23.4 Communication Errors Errors can occur during the message transmission on network,or in the content of the received messages. Depending on theerror type, inverter may answer or not to themaster:When the master sends amessage to an inverter configured atdetermined network address, the inverter will not response if:

Error in the parity bit.Error the CRC.Time out between transmitted bytes (3.5 times the timerequired for the transmission of a 11-bit word).

In thecase of asuccessful reception of the message, the inver-ter can detect problems and sendaerror message tothemasterindicating the problem that has been verified:

Invalid function (error code = 1): the requested function hasnot been implemented for the inverter.Invalid data address (error code = 2): the data address(register or bit) does not exist.Data value invalid (error code = 3): this error occurs in thefollowing conditions:- Value is out of permitted range.- Writing in data that cannot be changed (only read register,or register that does not allow changing with enabled inverter or bits of logic status).

- Writing in function of the logic command that has not beenenabled via serial interface.

Table 9.2 b) – Technical information about the inverter models13-16-24-30A/380-480V

Thevalues shown in thetablewerecalculated byconsidering therated inverter current, input voltage of 220V for the 200-240Vmodels and input voltage of 440Vfor the 380-480V models.

(2) Rated current is valid for the following conditions:Relative air humidity: 5% to 90%, non condensing.Altitude: 1000m (3300ft), up to 4000m (13200ft) with 10%derating/1000m (3300ft) of the rated current.Ambient temperature: 0ºC to 40ºC (32ºF to 104ºF) (up to50ºC (122ºF) with 2%/ºC derating of the rated current).The rated current values are valid for the switchingfrequencies of 2.5kHz or 5kHz (factory setting). For higherswitching frequencies, 10kHz and 15kHz, consider thevalues shown in the description of the parameter P297(referto chapter 6).

(3) Maximum Current:Inverter supports an overload of 50% (maximum outputcurrent = 1.5 x the rated output current) during 1 minute foreach 10 minutes of operation. For higher switchingfrequencies, 10kHz and 15kHz, consider the values shownat the description of the parameter P297(refer to chapter6).

203


(4) Rated input current for single-phase operation.Note: The models CFW080016B2024...,CFW080026B2024..., CFW080040B2024...,CFW080073B2024 ... and CFW080100B2024 ... can beoperated both with single-phase voltage and three-phasevoltage without output current derating.

(5) Theindicated motor power ratings areonly orientativevaluesfor IV-pole motors and normal duty loads. The precise in-verter sizing must consider the actual motor nameplateand application data.
