It is theresponsibility of the operator to choose the type and frequency of the checkswithin the specified time period. The manner in which the test is conducted mustmake it possible to verify that the safety device is functioning perfectly in interac­tion with all components. Time period for cyclical testè 15.1 Technical data, safety engineering.Prior to initial commissioning, wire the control inputs of the safety sub­functionsSTO and SBC. The safety sub­functions STO and SBC are available on the CMMT­AS on delivery without the need for any additional parameterisation.2.2 Intended useThe servo drive CMMT­AS is intended for supply and control of AC servo motors.The integrated electronics permit regulation of torque (current), rotational speedand position. Use exclusively:– In perfect technical condition– In original condition without unauthorised modifications; only the extensions

described in the documentation supplied with the product are permitted– Within the limits of the product defined by the technical dataè 15 Technical data

– In an industrial environmentThe safety function might fail and malfunctions might occur if you do not complywith the parameters required for the ambient and connection conditions.

The CMMT­AS­...­S1 supports the following safety sub­functions in accordancewith EN 61800­5­2:– Safe torque off (STO)– Safe brake control (SBC)– Safe stop 1 (SS1), achievable with suitable safety relay unit and appropriate

circuitry of the servo driveThe safety sub­function STO is intended to switch off the torque of the connectedmotor, thereby preventing an unexpected restart of the motor.The safety sub­function SBC is intended to safely hold the motor and axis in posi­tion at standstill.The safety sub­function SS1 is intended for performing a rapid stop with sub­sequent torque switch­off.2.2.1 Application areasThe device is intended for use in an industrial environment. Outside of industrialenvironments, measures may need to be implemented for radio interference sup­pression, e.g. in commercial and residential/mixed­used areas.The device is intended to be installed in a control cabinet. The minimum degree ofprotection required for the control cabinet is IP54.The device can be operated in TN, TT and IT systems if certain requirements aremet.Information on allowed and prohibited mains types of system earthing and neces­sary measures for use in IT networks è Description Assembly, Installation.Safety sub­functions may only be used for applications for which the stated safetyreference values are sufficient è 15.1 Technical data, safety engineering.2.2.2 Permissible componentsThe logic supply must meet the requirements of EN 60204­1 (protective extra­lowvoltage, PELV).If holding brakes and clamping units without certification are used, the suitabilityfor the related safety­oriented application must be determined through a riskassessment.The motors must fulfil the requirements of EN 61800­5­2 appendix D.3.5 andD.3.6 and of EN 60204­1. Motors approved or specified by Festo for the CMMT­ASfulfil the requirements.The motor cables and brake lines must fulfil the requirements of EN 61800­5­2appendix D.3.1 and of EN 60204­1. Motor cables and brake lines approved byFesto for the CMMT­AS fulfil the requirements.2.3 Foreseeable misuse

Foreseeable misuse, general– Use outside the limits of the product defined in the technical data.– Cross­wiring of the I/O signals of more than 10 servo drives CMMT­AS.– Use in IT networks without insulation monitors for detection of earth faults.

If the device is operated in IT networks, the potential conditions will change inthe event of a fault (earth fault on the feeding mains supply). As a result, therated voltage of 300 V to PE – which has important implications for the designof insulation and network disconnection – will be exceeded. This error mustbe detected.

– Use of a diagnostic output for connection of a safety function.The diagnostic outputs STA and SBA are not part of the safety circuit. The dia­gnostic outputs are used to improve diagnostic coverage of the related safetysub­function. The diagnostic outputs may only be used in combination withthe related safe control signals (AND operation) plus a reliable time monitor­ing function in the safety relay unit for the purpose of switching additionalsafety­critical functions.

Foreseeable misuse of the safety sub-function STO– Use of the STO function without external measures for drive axis influenced

by external torques.If external torques influence the drive axis, use of the safety sub­function STOon its own is not suitable for stopping the axis safely. Additional measuresare required to prevent dangerous movements of the drive axis, such as useof a mechanical brake in combination with the safety sub­function SBC.

– Disconnection of the motor from the power supply. The safety sub­function STO does not disconnect the drive from the powersupply as defined by electrical safety.

Foreseeable misuse of the safety sub-function SBC– Use of an unsuitable holding brake or clamping unit, also in view of:

– Holding or brake torque and emergency brake characteristics, if required.– Frequency of actuation

– Use of an unsuitable logic voltage supply2.4 Training of qualified personnelThe product may be installed and placed in operation only by a qualified electrotechnician, who is familiar with the topics:– installation and operation of electrical control systems– applicable regulations for operating safety­engineering systemsWork on safety­related systems may only be carried out by qualified personneltrained in safety engineering.2.5 CE markingThe product has the CE marking.

5.3 Safety sub-functions5.3.1 Function and applicationThe servo drive CMMT­AS­...­S1 has the following safety­related performance fea­tures:– Safe torque off (STO)– Safe brake control (SBC)– Safe stop 1 (SS1) with use of a suitable external safety relay unit and appro­

priate wiring of the servo drive– Diagnostic outputs STA and SBA for feedback of the active safety sub­func­

tion5.3.2 Safety sub-function STO

Function and application of STOThe safety sub­function STO switches off the driver supply for the power semicon­ductor, thus preventing the power output stage from supplying the energyrequired by the motor. The power supply to the drive is safely disconnected whenthe safety sub­function STO is active. The drive cannot generate torque and socannot perform any dangerous movements. With suspended loads or otherexternal forces, additional measures must be put in place to prevent movementsbeing performed (e.g. mechanical clamping units). In the STO state, the standstillposition is not monitored.The machines must be stopped and locked in a safe manner. This especiallyapplies to vertical axes without automatic locking mechanisms, clamping units orcounterbalancing.

NOTICE!If there are multiple errors in the servo drive, there is a danger that the drive willmove. Failure of the servo drive output stage during the STO status (simultaneousshort circuit of 2 power semiconductors in different phases) may result in a lim­ited detent movement of the rotor. The rotation angle/travel corresponds to apole pitch. Examples:• Rotating motor, synchronous machine, 8­pin è Movement < 45° at the motor

shaft• Linear motor, pole pitch 20 mm è Movement < 20 mm at the moving part

STO requestThe safety sub­function STO is requested on 2 channels by simultaneously switch­ing off the control voltage at both control inputs #STO­A and #STO­B.

STO feedback via STA diagnostic contactThe status of the safety sub­function STO can be reported to the safety relay unitvia the STA diagnostic output.The STA diagnostic output indicates whether the safe status has been reached forthe safety sub­function STO. The STA diagnostic output switches to high levelonly when STO is active on 2 channels via the control inputs #STO­A and #STO­B.

#STO-A #STO-B STA

Low level Low level High level

Low level High level Low level

High level Low level Low level

High level High level Low level

Tab. 7 Level of STAIf protective functions are triggered on both channels (STO­A and STO­B), e.g. ifthe voltage at STO­A and STO­B is too high, the internal protective functionsswitch off and STA also delivers a high level signal. Recommendation: the safety relay unit should check the status of the diagnosticoutput whenever there is a STO request. The level of STA must change accordingto the logic table. The safety relay unit can cyclically test the signals #STO­A and#STO­B for high level with low test pulses and for low level with high test pulses.5.3.3 Safety sub-function SBC

Function and application of SBCThe safety sub­function SBC provides safe output signals for the control of brakes(holding brakes or clamping units). The brakes are controlled on 2 channels byswitching off the voltage at the following outputs:– Safe output BR+/BR– [X6B] for the holding brake of the motor– Safe output BR­EXT/GND [X1C] for the external brake/clamping unitThe holding brake and/or clamping unit engage and slow the motor or axis. Thepurpose of this is to slow down dangerous movements by mechanical means. Thebraking time is dependent on how quickly the brake engages and how high theenergy level is in the system.The use of just one brake is only possible when performance requirements arelow è Tab. 52 Safety reference data for the safety sub­function SBC. To do this,connect the brake either to BR+/BR– or to BR­EXT.

NOTICE!If there are suspended loads, they usually drop if SBC is requested simultan­eously with STO. This can be traced back to the mechanical inertia of the holdingbrake or clamping unit and is thus unavoidable. Check whether safety sub­func­tion SS1 is better suited to your application.

SBC may only be used for holding brakes or clamping units which engage in thede­energised state. Ensure the lines are installed in a protected manner.

SBC requestThe safety sub­function SBC is requested on 2 channels by simultaneously switch­ing off the control voltage at both control inputs #SBC­A and #SBC­B:

– The #SBC­A request switches off the power to the signals BR+/BR­.– The #SBC­B request switches off the power to the signal BR­EXT.In the event of a power failure in the logic voltage supply of the servo drive, poweris also cut off to the brake outputs.

SBC feedback via SBA diagnostic contactThe 2­channel switching of the brake is indicated via the SBA output. SBA is usedto report the status of the safety sub­function SBC for diagnostic purposes,e.g. by reporting it to an external safety relay unit.The SBA diagnostic output indicates whether the safe status has been reached forthe safety sub­function SBC. It is set if the following two conditions are fulfilled: – Switching off of both brake outputs is requested (#SBC­A = #SBC­B = low

level)– The internal diagnostic functions have determined that there is no internal

error and both brake outputs are de­energised (switched off).

Testing the safety sub-function SBCTest inputs #SBC­A and #SBC­B separately from each other and together. The dia­gnostic feedback may only be set to high level when inputs #SBC­A and #SBC­Bare both requested. If the signal behaviour does not correspond to expectations,the system must be put into a safe condition within the reaction time. It is essen­tial that time monitoring be provided in the safety relay unit.The safety sub­function SBC with feedback via SBA must be tested at least 1xwithin the space of 24 h.• Test SBA feedback based on the SBC­A and SBC­B level according to the fol­

lowing table.

#SBC-A (BR+) #SBC-B (BR-Ext) SBA

Low level Low level High level

Low level High level Low level

High level Low level Low level

High level High level Low level

Tab. 8 Testing all SBC levelsWhile you are testing the safety sub­function SBC, discrepancy error detectionmay be activated in the CMMT­AS if the test lasts longer than 200 ms. If a corres­ponding error message is output by the basic unit, you will need to acknowledgeit.

Evaluation of SBARecommendation: Evaluation with every actuation.• Check SBA feedback whenever there is a request.

Requirements for the brakeRequirements for the brakeè Description Safety sub­function

Brake test• Check whether a brake test is required. The DGUV information sheet “Gravity­

loaded axis” provides information on this.5.3.4 Safety sub-function SS1Together with a suitable safety relay unit, the following can be achieved:– Safe stop 1 time controlled (SS1­t); triggering of motor deceleration and, after

an application­specific time delay, triggering of the safety sub­function STOSafety sub­function SS1 è Description Safety sub­function5.3.5 Fault exclusionPut suitable measures in place to prevent faulty wiring:– Exclude wiring faults in accordance with EN 61800­5­2– Configure the safety relay unit to monitor the outputs of the safety relay unit

and wiring up to the servo drive5.3.6 Safety relay unitUse suitable safety relay units with the following characteristics:– 2­channel outputs with

– Detection of shorts across contacts– Required output current (also for STO)– Low test pulses up to a maximum length of 1 ms

– Evaluation of the diagnostic outputs of the servo driveSafety relay units with high test impulses can be used with the following restric­tions:– Test impulses up to 1 ms in length– Test impulses are not simultaneous/overlapping on #STO­A/B and #SBC­A/B– The resulting safety­related classification depends on the evaluation of dia­

gnostic feedbacks STA, SBA è 15.1 Technical data, safety engineering,safety reference data STO and SBC.

1) To ensure that clearance H2 is observed and that the motor and encoder cables are routed in the optimummanner on the bottom of the housing, an installation clearance of 150 mm is recommended!

Tab. 11 Mounting distances and installation clearanceThis means that a minimum lateral distance of 2 mm (62 mm … 60 mm) must beobserved in relation to neighbouring CMMT­AS devices.For adjacent third­party devices, Festo recommends a distance of at least 10 mm(surface temperature of third­party device max. 40 °C). The double mating plugfor cross­wiring of the connection [X9A] protrudes by approx. 4 … 5 mm over theright side of the device. However, this does not create an obstacle for arrayingadditional CMMT­AS.

7.2 Installation

Assembly instructions– Use a control cabinet with degree of protection IP54 or higher.– Always install device vertically in the control cabinet on a closed surface

(mains supply lines [X9A] point upwards).– Screw device flat to a sufficiently stable mounting surface so that good heat

transfer from the cooling element to the mounting surface is ensured(e.g. screw to the rear wall of the control cabinet).

– Maintain minimum distances and installation clearance to guarantee suffi­cient air flow. The ambient air in the control cabinet must be able to flowthrough the device from bottom to top without hindrance.

– Take into account the required clearance for the wiring (connecting cables ofthe device must be routed from above and from the front).

– Do not mount any temperature­sensitive components near the device. Thedevice can become very hot during operation (switch­off temperature of thetemperature monitoring function è Technical data).

– When assembling several devices in a device compound, consider generalrules for cross­wiring. For DC link coupling, higher­power devices must beplaced closer to the mains supply.

To enable attachment to the rear panel of the control cabinet, the servo drivecooling element has a slot on the top in the shape of a keyhole and an ordinaryslot on the bottom.

Danger of burns through hot escaping gases and hot surfaces.In case of error, incorrect wiring or incorrect polarity of the connections [X9A],[X9B] and [X6A], internal components can be overloaded. High temperatures candevelop and hot gases can be released.• Have an authorised electrician perform the installation according to the docu­

mentation.

WARNING!

Danger of burns from hot housing surfaces.Metallic housing parts can accept high temperatures in operation. In particular,the braking resistor installed in the profile on the back side can become very hot.Contact with metal housing parts can cause burn injuries.• Do not touch metallic housing parts.• After the power supply is switched off, let the device cool off to room temper­

ature.

• Mount the servo drive on the backwall of the control cabinet with suitablescrews while complying with the assembly instructions.

8 Installation8.1 Safety

WARNING!

Risk of injury from electric shock.Contact with live parts at the power connections [X6A], [X9A] and [X9B] can resultin severe injuries or death.• Do not pull out power supply plugs while live.• Before touching, wait at least 5 minutes after switching off the load voltage to

allow the intermediate circuit to discharge.

WARNING!

Risk of injury from electric shock.The leakage current of the device to earth (PE) is > 3.5 mA AC or 10 mA DC.Touching the device housing if there is a fault can result in serious injuries ordeath.Before commissioning, also for brief measuring and test purposes:• Connect PE connection on the mains side at the following positions:

– Protective earth connection (earthing screw) of the housing– PE pin of the connection [X9A] (power supply)

The cross section of the PE conductor must be at least equal to the crosssection of the mains conductor L at [X9A].

• Connect motor cable to connection [X6A] and the shield of the motor cable onthe front side to PE via the shield clamp of the servo drive.

• Connect all additional PE conductors for the connections used.• Observe the regulations of EN 60204­1 for the protective earthing.

WARNING!

Danger of burns through hot escaping gases and hot surfaces.In case of error, incorrect wiring or incorrect polarity of the connections [X9A],[X9B] and [X6A], internal components can be overloaded. High temperatures candevelop and hot gases can be released.• Have an authorised electrician perform the installation according to the docu­

mentation.

WARNING!

Risk of injury from electric shock in the event of incomplete insulation at thepower connections [X6A], [X9A] and [X9B].Before operating, plugging in or unplugging the operator unit CDSB or a connect­or from a hot­plug­capable interface, the following points must be fulfilled:• The conducting lines at the device are completely insulated.• The protective earthing (PE) and the shield connection are correctly connec­

ted to the device.• The housing is free of damage.

WARNING!

Risk of injury due to overheating and electric shock with faulty live componentsClosing the branch­circuit protective device with faulty live components maycause fire or electric shock.• The opening of the branch­circuit protective device may be an indication that

a fault current has been interrupted. To reduce the risk of fire or electricshock, current­carrying parts and other components of the controller shouldbe examined and replaced if damaged. If burnout of the current element of anoverload relay occurs, the complete overload relay must be replaced.

NOTICE!Check the safety functions to conclude the installation process and after everymodification to the installation.

During installation of safety­related inputs and outputs, also observe the follow­ing:– Meet all specified requirements, e.g.:

– Surrounding area (EMC)– Logic and load voltage supply– Mating plug– Connecting cables– Cross­wiring

– Additional information è Description Assembly, Installation.– The maximum permissible cable length between the safety relay unit and the

plug of the I/O interface is 3 m. – During installation, make sure you meet the requirements of EN 60204­1. In

the event of a fault, the voltage must not exceed 60 V DC. The safety relayunit must switch off its outputs in the event of a fault.

– Carry out wiring between the safety relay unit and the I/O interface of theservo drive in such a way as to exclude the risk of a short circuit between theconductors or to 24 V, as well as a cross circuit è EN 61800­5­2, AnnexD.3.1. Otherwise, the safety relay unit must feature detection of shorts acrosscontacts and, in the event of a fault, must switch off the control signals on 2channels.

– Only use suitable mating plugs and connecting cables è DescriptionAssembly, Installation.

– Avoid conductive contamination between neighbouring plug pins. – Make sure that no bridges or similar can be inserted parallel to the safety wir­

ing. For example, use the maximum wire cross section or appropriate plasticwire end sleeves.

– To cross­wire safety­related inputs and outputs, use twin wire end sleeves.When cross­wiring inputs and outputs, a maximum of 10 devices may becross­wired è Description Assembly, Installation.

– The safety relay unit and its inputs and outputs must meet the necessarysafety classification of the safety function that is required in each case.

– Connect each of the control inputs to the safety relay unit on 2 channels usingparallel wiring.

– Only use permitted motor cables for the connection BR+/BR– .– If the diagnostic output of the safety sub­function concerned has to be evalu­

ated: connect diagnostic output directly to the safety relay unit. Evaluation ofthe diagnostic output is either mandatory or optional depending on whichsafety classification is desired.

– If diagnostic outputs are cross­wired for a device compound: wire diagnosticoutputs as a ring. Guide the two ends of the ring to the safety relay unit andmonitor for discrepancies.

8.2 Residual current protective device

1) To comply with the mains harmonics requirements of EN 61000­3­2, it is necessary to install a line chokewith three partial windings for mains supply lines L1, L2 and L3 (3 x ³ 3.7 mH).

2) With motor cable lengths > 25 m, use suitable wire cross sections when connecting the motor phases. Payattention to the nominal currents, maximum currents and voltage drop. Take account of the voltage dropon the brake cables. Adhere to the maximum permissible cable length for the encoder used.

Tab. 14 Category according to the cable length– If set­up and commissioning are performed by a professional with the neces­

sary experience for setting up and commissioning drive systems, includingtheir EMC aspects, category C2 devices can be used in the first environment(residential area).

– When operating category C2 devices, limit values apply to the harmonic cur­rents in the mains supply (EN 61000­3­2 or EN 61000­3­12). Please checkwhether this is the case for your facility/system. As a rule, compliance withthe limit values for harmonic currents requires the use of external filter meas­ures, e.g. installation of a line choke.

– Category C3 devices are intended for use in the second environment only(industrial environment). Use in the first environment is not permitted.

This product can generate high­frequency malfunctions, which may make it neces­sary to implement interference suppression measures in residential areas.Additional information on EMC­compliant installation è Description Assembly,Installation.

Fig. 10 Shared shield support of all cable shields (example)

Option 2: the outside shield of the motor cable is connected separately over alarge surface area below the shield clamp on the front of the CMMT­AS. The insideshields are connected separately to the designated PE pin of the connection[X6B].• Make unshielded cable ends as short as possible.

Mounting the shield clampThe lower area on the front of the housing is used as a shield support surface. Theshield support surface, together with the shield clamp, allows the motor cableshield to be connected over a large surface area.1. Using the shield clamp, press the motor cable shield or the conducting shield

end sleeve of the motor cable onto the shield support surface of thehousing è Fig.11.

9 Commissioning9.1 Safety

WARNING!

Risk of injury from electric shock in the event of incomplete insulation at thepower connections [X6A], [X9A] and [X9B].Before operating, plugging in or unplugging the operator unit CDSB or a connect­or from a hot­plug­capable interface, the following points must be fulfilled:• The conducting lines at the device are completely insulated.• The protective earthing (PE) and the shield connection are correctly connec­

ted to the device.• The housing is free of damage.

WARNING!

Severe, irreversible injuries from accidental movements of the connected actu-ator technology.Unintentional movements of the connected actuator technology can result fromexchanging the connecting cables of a servo drive or between servo drives.• Before commissioning: All cables must be correctly assigned and connected.

WARNING!

Risk of injury from electric shock.Contact with live parts at the power connections [X6A], [X9A] and [X9B] can resultin severe injuries or death.• Do not pull out power supply plugs while live.• Before touching, wait at least 5 minutes after switching off the load voltage to

allow the intermediate circuit to discharge.

NOTICE!During commissioning: Keep the range of movement of the connected actuatorsclear, so that no persons are endangered.

Use of safety functions

NOTICE!The safety sub­functions STO and SBC are already available on the CMMT­AS ondelivery without the need for any additional parameterisation. Prior to initial com­missioning, you must – as a minimum – wire safety sub­functions STO and SBC.

1. Make sure that each safety function of the system is analysed and validated.It is the responsibility of the operator to determine and verify the requiredsafety classification (safety integrity level, performance level and category) ofthe system.

2. Put the servo drive into operation and validate its behaviour in a test run.During integration of the PDS, observe the measures stipulated by standardEN ISO 13849­1, Chapter G.4:– Functional test– Project management– Documentation– Performance of a black­box test

NOTICE!

Unauthorised access to the device can cause damage or malfunctions.When connecting the device to a network, protect the network from unauthorisedaccess.Measures to protect the network include: • Firewall• Intrusion Prevention System (IPS)• Network segmentation• Virtual LAN (VLAN)• Virtual Private Network (VPN)• Security at physical access level (Port Security)

For additional information è Guidelines and standards for security in informationtechnology, e.g. IEC 62443, ISO/IEC 27001.

9.2 Preparation for commissioningFor initial commissioning, you will need to have the Festo Automation Suite soft­ware installed along with the CMMT­AS plug­in  è www.festo.com/sp.

Prepare for commissioning as follows: 1. Check wiring of the CMMT­AS.2. Install Festo Automation Suite plus CMMT­AS plug­in on the PC.3. Create project and add CMMT­AS device.4. Establish connection to the CMMT­AS and set network configuration.5. Identify the technical data of the components that is required for configura­

tion.9.3 Commissioning steps

NOTICE!

Unwanted drive movements or damage to components.Incorrect parameterisation may result in unwanted drive movements or overloadwhen the closed­loop controller is enabled or may lead to connected componentsbecoming overloaded or damaged.• Do not enable the closed­loop controller until the configured components

(servo drive, motor, axis, etc.) match those that are connected exactly.

During initial commissioning with the Festo Automation Suite with the CMMT­ASplug­in installed, the following steps must be performed, for example:1. Perform configuration and parameterisation with the CMMT­AS plug­in (hard­

ware configuration, critical limits and parameters).2. If the safety function is being used, check functioning of the safety functionsè Description Safety sub­function.

3. Check signal behaviour of the digital inputs/outputs (e.g. limit/referenceswitch).

4. Provide required control signals.5. Check direction of rotation/direction of travel of the electromechanical drive

(e.g. in jog operation).6. Carry out homing.7. Test positioning behaviour (test mode, è help for the CMMT­AS plug­in).8. If necessary, optimise controller setting (optional, è help for the CMMT­AS

plug­in).9. Perform fieldbus configuration and test control profile (è description of the

device profile used).10. Complete commissioning (e.g. save project with Festo Automation Suite and

archive project).

10 OperationCheck the safety functions at adequate intervals for proper functioning. It is theresponsibility of the operator to choose the type and frequency of the checkswithin the specified time period. The manner in which the test is conducted mustmake it possible to verify that the safety device is functioning perfectly in interac­tion with all components. Time period for cyclical testè 15.1 Technical data, safety engineering.The CMMT­AS is maintenance­free during its period of use and specified servicelife. The test interval varies from one safety sub­function to another:

– STO: no test has to be carried out during the period of use, but we recom­mend evaluating STA whenever the sub­function is requested to ensure max­imum diagnostic coverage and the highest safety­related classification.

– SBC: cyclical test required at least once every 24 h and SBA evaluationrecommended whenever the sub­function SBC is requested to ensure maxim­um diagnostic coverage and the highest safety­related classification.
