A detailed description of the protections and the related visualizations is given inparagraph _3.7 Operational statuses and their signals

Functional diagram of the protections:

Note :


_2.2.2 Digital Inputs

The drives LW1A4080N0A1 are equipped with 4 digital inputs for the control of thefunctions:

• Boost current BOOST• Enabling of the power stage EN• Step (or CLK_UP) STEP• Direction (or CLK_DWN) DIR

The functionality of the inputs depends on the settings of dip-switches DIP2Refer to paragraph _3.5.2 User configurations for details.

BOOST : increase the phase current of 20%.BOOST input closed, the drive increases the phase current of 20% from phase current setting.BOOST input open, the phase current is the nominal phase current setting.The BOOST current function is useful during the acceleration and deceleration time and while the load on the motor is variable.

The phase current in the motor, can NOT exceed the max current value of the drive(8ARMS/11,28APK). If the nominal current is greater then 6.5ARMS,, the boost current value isalways 8ARMS.Choose the motor type depending on BOOST current function.

EN – ENABLE : enable or disable the current in the motor in function of the status of DIP2 SW3

DIP2 SW3=OFF disable mode = dis ables the motor current.The current in the motor is disabled when input ENABLE is closed.

DIP2 SW3=ON enable mode = enables the motor current.The motor current is enabled when the ENABLE input is closed.

When the current in the motor windings is zero, no maintenance torque is supplied(Holding Torque) and the load can drag the motor shaft.In applications where in a maintenance torque is necessary at stand still of the motor,keep the winding current at motor stand still or provide a braking system

STEP – Step or CLK_UP : the motor executes a step f or each switch of this input. The function depends on the status of DIP2 S W1-2

DIP2 SW1=OFF Rising Edge = STEP and DIR inputs active on the ris ing edge. The motor executes a movement of one step when the STEP input is engaged.

DIP2 SW1=ON Falling Edge = STEP and DIR inputs active on t he falling edge. The motor executes a movement of a step when the STEP input is opened.

DIP2 SW2=OFF STEP&DIRECTION: input STEP=STEP, input DIR = Direct ion. The motor executes a movement in steps equal to the number of pulses applied to the STEP input. To change the motion direction, it's necessary to change the DIR input status.

DIP2SW2=ON Clock_UP&Clock_DOWN: input STEP=CLK_UP, input DIR = CLK_DWN.


i

i

The motor executes a movement in a direction when the step pulses are applied to the STEP (CLK_UP) input and in the opposite direction when they are applied to the DIR (CLK_DWN) input.

For more information on the operating mode, refer to paragraph _3.5.2 User configurations.

NOTE: the clockwise or anti-clockwise rotation direction of the motor depends, besides onthe inputs statuses, also on the connection of the motor windings. To avoid wrongmovements and possible damages, the rotation direction must be checked before fixatingthe motor to the load.

Steps per Rotation TableThe type of step angle defines the angular resolution of the motor and it is usually set toachieve the desired positioning accuracy and smoother motion, vibration-free with a lowerstep angle and a higher frequency.In a 2-phase motor with 50 pole pairs, each step pulse corresponds to a rotation of 1.8°full step, 0.9° half step, and so on.Choosing the Full Step will get the highest value of RMS current in the windings of themotor with maximum torque achievable, but at certain step frequencies is possible thatthere are torque falls, due to resonances depend on the motor or load characteristics.

The rotation measured in degrees of the motor shaft, for every single step pulse dependson the settings of DIP1 SW5-6-7-8 (refer to paragraph _3.5.2.2 Step angle setting).The following table shows the number of necessary step pulses to let the motor shaftexecute a full rotation (360°) and the rotation in degrees executed by the motor shaft atevery step pulse (the table refers to 50 poles motors, 1.8° per full step).The following formula defines the step frequency F(Hz) depending on motor speed (RPM)F = (RPM / 60) x ((360° / Full Step Degrees / Step Setting))

For example, the step frequency to obtain speed rotation of 150 RPM, with a motor of 1.8°driven with 1/8 step is:

F = ( 150 / 60 ) x ( ( 360° / 1.8° ) / 1/8 ) ) = 4000 Hz

Step type Steps per rotation Step degree

Full Step 200 1,8°

1/2 step 400 0,9°

1/4 step 800 0,45°

1/8 step 1600 0,225°

1/16 step 3200 0,1125°

1/32 step 6400 0,05625°

1/64 step 12800 0,028125°

1/128 step 25600 0,0140625°

1/256 step 51200 0,00703125°

1/5 step 1000 0,36°

1/10 step 2000 0,18°

1/25 step 5000 0,072°

1/50 step 10000 0,036°

1/125 step 25000 0,0144°

1/250 step 50000 0,0072°

DIR – Direction or CLK_DWN : rotation direction of t he motor. The function depends on the status of DIP2 SW1-2


i

See notes about DIP2 SW1-2 related to the STEP input.

NOTE: the clockwise or anti-clockwise rotation direction of the motor depends, besides onthe DIR input status, also on the connection of the motor windings. To avoid wrongmovements and possible damages, the rotation direction must be checked before fixatingthe motor to the load.

The 4 digital inputs of the drive are optoisolated with bandwidth to 200KHz and they canbe used with 5VDC±10% PNP, NPN, Push-pull or Line Driver and 24VDC±25% PNP/Push-Pull only changing the connector connection.

Digital inputsschematic:

For input at 5VDC, you must connect between +INn vs -INn ;For input at 24VDC PNP o Push-Pull, you must connect to +INn by linking COM_IN withVSS (reference of +24V); this precludes the possibility of using other inputs at 5V NPN.For inputs with voltage between 5VDC÷24VDC or 24VDC NPN inputs, you must connect between +INn vs -INn by inserting a limiting resistance in series as show in the table:

VINPUT REXT

5VDC 0 Ω12VDC 470 Ω 0.25W15VDC 680 Ω 0.5W20÷24VDC 1200 Ω 0.5W

For different input voltages, use the next formulas to calculate the resistive value andpower of the resistances to insert in series: REXT = ((VINPUT - 1.25) / 0.017) – 220 PR_EXT = ((VINPUT – 1.25) / (REXT + 220)) ² * REXT

Example for VINPUT =36V :REXT =((36-1.25) / 0.017)–220 = 1824 Ω => approximate the commercial value of 1K8PR_EXT = ((36 – 1.25) / (1800 + 220)) ² * 1800 = 0.533W => approximate the commercialvalue of 1 W.

_3.1 Safe installation and use of the unit

Only qualified staff is allowed to install the LW1A4080N0A1 drives, after having readand understood the information in this manual. The installation instructions have to befollowed and approved. Eventual doubts need to be clarified with the supplier of theequipment before using.

EVER will not take any responsibility for indirect damage due to negligence, wronginstallation, modifications to the product without approval or wrong connections of theequipment to the wiring.

SECURITYIn particular, the user must:

• Remove the power supply before realizing or removing a connection:

• Not work on the drive without that has been realized a ground connection for thedrive and the motor. The Protective Earth connection (PE) has to comply with thelocal requirements in force.

• Not establish connections to the internal circuit of the drive;

• Wait until the green LED light of POWER_ON is switched off before manipulating orexecuting maintenance to the drive;

• Not use the digital ENABLE input as safety stop. Always remove the power supplyvoltage from the drive to establish a safe switching off;

• Pay attention to the heat loss of some parts of the drive: using the drive in extremeapplications, some surfaces reach high temperatures. Before disconnecting thedevice, wait until it has cooled down;

• In case of missing voltage the motor is not able to keep the load: it's thus forbidden touse the motor if the condition of missing holding torque of the motor can create adangerous situation, unless the user provides special devices to block the load.

The negative pole of the power supply is NOT connected to the ground through aninternal connection to the drive. If this default connection doesn't suit the requirementsof the application, the user needs to refer to [email protected] for thenecessary technical information.


i i

ELECTROMAGNETIC COMPATIBILITYTake all precautions and requirements which are necessary for the compliance with theelectromagnetic compatibility.

Some disturbances generated by other insufficiently filtered and/or shielded equipment,can cause malfunctions in the drive which can result into uncontrolled movements.

When making the connections, take into account the requirement of paragraph _3.5.1.4Guideline for wiring.

When the emissions generated by the working drive are not adequately filtered, the correctfunctioning of other devices can be disturbed.

The final user, taking into account the requirements of your application, will consider theinstallation of an adequate filtration system (network filter).

Example of multi-axes (for simplicity is the power supply +24Vdc is not specified ) :

AC IN : input for the AC power supply of the power part (motor) It can be single or three phase AC power supply.

PE : Environmental Protective Earth.

+24 – VSS : power supply for the digital outputs and Std inputs.For applications where in no digital outputs and Std inputs are used, this power supply section can be left out.

B0_COM_IN : reference for the digital inputs. Generally associated with VSS of the digital outputs. If they are not used, inputs of 24V, BO_COM_IN have to remain disconnected.

Main characteristics of the drive power supply:

AC network is a recommended safety device.Switch:

Primary use fuses on the AC bus or an equivalent safety switch.protections:

Surge on the primary circuit, they protect the drive against Surges coming from suppressors: the primary network power supply.

EMC Filter: is generally necessary to satisfy the EMC compatibility requirementsrelated to the emissions. An EMC filter is recommended in case ofsensible circuits powered by an AC line. If a commercial line filter ischosen, one needs to take into account the total RMS current of thepowered system.

The AC line filter needs to be installed following the builder's directives.Generally, the filter needs to be inserted between the principal AC line andthe transformer, if the last one is positioned near the drive or to theelectrical cabinet, between the transformer and the rectifier bridge in theother cases, keeping the bridge near the drive, and keeping theconnection between the filter and the transformer as short as possible.

Transformer: The primary circuit of the transformer must be dimensioned in function ofthe characteristics of the AC power supply line. The voltage peaks on thesecondary circuit of the transformer are equal to 1.41*secondary RMSvoltage. The AC power supply voltage must not exceed the Vac powersupply voltage of the drive.

DON'T use an Auto-transformer to interface with the electricnetwork. Only a transformer guarantees the galvanic isolationnecessary for electrical safety.

The power of the transformer depends on the power required by themotor: to define the motion characteristics under control (dimensioning ofthe power supply and the motor), it's possible to contact our supportdepartment by the e-mail address: [email protected]. Alternatively the following procedure can be used to define approximatelythe power supply characteristics:1. Power to the motor shaft for every axle in watts:

Wn =π*Nn[RPM]*Tn[Nm]/30 2. Power to the total load in watts :

WS = sum of the Wn of the axles moving simultaneously;3. Power of the transformer in watts:

TW = 2 * WS (efficiency = 0.5)4. power of the transformer in VA:

TVA=TW / 0,7 (single phase) or TVA= TW / 0,8 (three phase);5. Take into account a voltage drop of about 8% for the transformer

during the application of the load (the secondary voltage must notexceed a voltage value of 108% of the nominal value when the loadis zero).

A simple and fast alternative method to calculate the power in VA of the transformer is: TVA(VA) = √2*VdcBUS*ImaxPHASE(RMS)

Secondary Must be placed before the rectifier bridge and must be calibratedprotections: depending on the set phase current. Instead of the secondary protections

can be used an automatic safety switch.

Secondary used to cut only a few voltages (such as power supply, leaving the otherSwitch : side of the transformer connected).

_3.3 Choosing the stepper motor


EMC

i

The LW1A4080N0A1 drive have been designed to function with 2 phase stepper motorswith the following characteristics:

• The nominal winding current for the drive


MIN. TYP. MAX.

Motore corrente 1.0 8.0 ARMS Dip-Switches setting

1.41 11.28 APK

• With connection of the Bipolar Parallel windings: the motor is supplied by the drivewith a winding current equal to 1.41 times the unipolar nominal current (IPHASE * 1.41).

• With connection of the Bipolar Series windings: the motor is powered by the drivewith a winding current equal to 0.7 times the unipolar nominal current (IPHASE * 0.70).

The stepper motor is chosen on base of a series of variables that depend on theapplication: torque required by the shaft, speed, dimension of the motor, current,inductance etc.

The dynamic performance of the motors depends on the voltage: at higher voltage performance increases.

_3.4 Assembling of the drive

For wall mounting, refer to figures listed at paragraph_2.1 Mechanical and environmentalUse the M4 screws to fix the drive to a wall of the electric cabinet.

The environment in which the drive will be installed needs to be free of impurities,corrosive vapour, gases or liquids. Avoid environments where in vapour and humiditywill condensate.

When installing the drive in an electrical switchboard, make sure that the opening of the air stream or the cooling system of the switchboard doesn't make the internal temperature rise above the maximum allowed working temperature.

Every local security aspect concerning the installa tion of the drive has to beconsidered a project standard for the electrical sw itchboard.

Assembling Guide The installation has to meet at least the following requirements:

� maintain the vertical orientation of the drive;� avoid excessive vibrations or shocks;� Foresee free space for the air stream above and under the drive;� Respect the minimal distances indicated in the following figure;

The cooling of the drives LW1A4080N0A1 occurs mainly through radiation of the heat sink fins and secondary, by means of contact through the clamping surface of the electrical switchboard.An insufficient heat exchange can increase the drive temperature until the threshold of the heat protection, including a system block reported by the display. In the installation project, this two dissipation channels need to be optimized.

The next page shows the minimum distances to be respected in the project instrallation.

_3.5.1.4 Guideline for wiring

Guideline for wiring Effect

Connect the earthing terminal of CN10.3 to the main terminal of Protective Earthing (PE) of the installation.

Connection necessary for electrical safety.Increases the resistance for: irradiated disturbances and electrostatic flushes (ESD).

Use shielded cables for the command signals.(digital and analog inputs and communication interfaces)

Increases the resistance against disturbances and reduces the irradiated and conducted emissions.

Connect the shields of the signal cables from both ends to the ground.

Increases the resistance against disturbances and reduces the irradiated and conducted emissions. In some applications, depending on the lay-out of the machine, it can be more effective to connect the screen from one side.

The use of shielded cables is also recommended for theconnection of the motor. When a shielded cable is used for the motor, connect the screen to terminal CN10.3 and not to the body of the motor.

Increases the resistance against disturbances and reduces the irradiated and conducted emissions.

Connect the body of the motor to the ground with a special cable. The body of the motor and the shield of the cable have to be connected to the ground terminal with 2 separated cables.

Necessary connection for the electric security. Reduce the conducted emissions.

Powering different drives with a single power supply, create a star connection to each drive to the terminals ofthe capacitor of the power supply filter (in the centre of the star).

Reduces the disturbances due to pulse current.

Maintain the connections (cables) as short as possible and avoid ground loops.

Increases the resistance against disturbances and reduces irradiated and conducted emissions.

The paths of the signal cables and controls must be separated and/or shielded from motor cables and powersupply to avoid that the inductive coupling can cause incorrect operations.

Increases the resistance against disturbances.


_3.5.2 User configurations

_3.5.2.1 Phase Current

The phase current has up to 15 different levels through DIP1 SW1-2-3 and on DIP2 SW4.The DIP2 SW4 setting defines the phase current range 1.0 ÷ 4.5 ARMS or 5.0 ÷ 8.0 ARMS while DIP1 SW1-2-3 define phase current value.

Factory setting = phase current null (DIP1 SW1-2-3=OFF and DIP2 SW4=OFF).

NOTE : the drive sets RMS (ARMS) phase current value. The peak phase current (APK) is defined by form factor (FF=1.41 for any step angle but it is FF=1 for Full Step).About Full Step: the peak phase current is the same of RMS (ARMS).

_3.5.2.3 Reduction of the phase current (RWC)

It reduces the current consumption and motor heating and drive, when the motor is standstill. The motor keep an reduced holding torque

DIP1 Default FunctionSW4OFF X RWC ON : the motor phase current will be reduced to 60% of the nominal

value 1 second after the last step pulse. The current in the motor returnsautomatically to the nominal value after the first pulse of the external step hasbeen sent to the drive.

ON RWC OFF : if the motor stand still, the phase current is at nominal current.

Check if the reduce holding torque is enough for specific application

_3.5.2.4 Selection active front STEP and DIR inputs

It's possible to choose the active front of the STEP and DIR and to choose if the step execution is executed at the engagement of the input or at its disengagement :

DIP2 Default FunctionSW1OFF X Rising Edge : step execution when input becomes close

ON Falling Edge : step execution when input becomes open

_3.5.2.5 Step/DIR or CLK_UP/CLK_DWN mode

Defines the digital inputs STEP e DIR functions:

DIP2 Default FunctionSW2OFF X STEP/DIR : step sequence must be supplied to the STEP input, while the

rotation direction of the motor depends on the DIR status (Direction).

ON CLK_UP/CLK_DWN : STEP input is CLK_UP function and DIR input isCLK_DWN function. Step sequence on STEP input the motor run in a direction,step sequence on DIR input the motor run in the opposite direction.


_3.5.2.6 EN input mode

Defines the EN (ENABLE) input mode:

DIP2 Default FunctionSW3OFF X DISABLE : the motor is energized by opening the EN input (ENABLE). It's

possible to leave the EN input disconnected to have the functioning of theDrive.

ON ENABLE : engage the EN input to enable to power stage of the Drive.

_3.6 First start up procedure

• Check all connections: power supply, motor and control logic.

• Make sure that the application settings are correct.

• The factory setting (all Dip-Switches “OFF”), disab le any type of motor run untilthe suer sets the correct setting The display shows “S” lblinking and FAULT output is open.

• Make sure that the AC power supply characteristics of the motor are suitable for the drive.

• Make sure that the DC power supply characteristics of the I/O are suitable for the drive.

• If possible, remove the load from the motor shaft to avoid that wrong movements cause damage.

• Power and make sure that the display is switched on.If the display remain off, turn down the system immediately and verify if all connections are present and if they are correct.

• Enable the current to the motor and verify if the torque is present.

• Execute a movement of some steps and verify if the rotation direction is the desired one. To reverse the rotation direction of the motor shaft, reverse the connection of one of the motor phases, for example A with A/, after having removed the power supply.

• Remove the power supply, fixate the motor to the load and check the full functionality.
