Circuitry without use of the STO safety function
If you do not need the integrated safety function STO in your application,
to operate the motor controller you must bridge Pin 1 and Pin 2 at the X3
interface.
This deactivates the integrated safety function!
With this circuitry, safety in the application must be ensured through other
appropriate measures.
Use of the STO safety function
For intended use of the safety function STO – “Saf e Torque Off ”, observe
the information in the STO description GDCP-CMMS-AS-G2-S1-...
Use the “Safe Torque Off ” function (STO) whenever you have to reliably disconnect
the energy supply to the motor in your part icular application. To ensure the func-
tion STO “Safe Torque Off ”, the c ontrol ports DIN4 [ X1.21] and Rel [X3.2] must be
connected in two channels through parallel wiring. This interface can be part of an
emergency stop c ircuit or a protective door arrangement, for example.
Recommendation for initial start-up without safety equipment:
Minimum circuitry with emergency stop switching device and two-channel switch-
off via the control ports REL [X3.2] and DI N4 [ X1.21] .
Note
Loss of the safety function.
Lack of the safety function can result in serious, irreversible injuries, e.g. due to
uncontrolled movements of the connected actuator technology.
– The STO function request must always run over X3.2 and X1.21 (end stage
enable).
– If uncontrolled coasting can result in a hazard or damage, additional meas-
ures a re required.
– A clamping unit is actuated by the non-safety-relevant firmware of the CMMS-
AS -...-G2 motor controller.
• Make sure that no jumpers or the like can be inserted parallel to the safety
wiring, e.g. through the use of the maximum wire c ross section of 1.5 mm² or
suitable wire end sleeves with insulating collars.
• Use twin wire end sleeves for looping through lines between neighbouring
devices.
• Comply with the specified environmental and connection conditions, in partic-
ular the input voltage tolerances.
• Place the motor controller in operation only if all safeguarding, including the
safety function, has been installed and checked.
• The safe ty function must be checked and, prior to the intended use, a corres-
ponding v alidation must be carried out.

1) In the motor and connecting cable, reliable separation of the motor temperature sensore from the motor
circuit must be ensured.
If third-party cables are used: Place the complete screening of the motor-
side c able f lat on the plug or motor housing. Length ≤ 40 mm.
• Place the c omplete screening of the motor c able at the screening con-
nection terminal of the related motor controller so that the leaked cur-
rent can flow back into the controller causing it
• Do not use the complete screening as strain relief.
Connection of a holding brake
Holding brakes are not appropriate for braking the motor. They only serve
functional holding of the motor shaft. Additional measures are required for
use in safety-oriented applications.
4.7 Power supply [X9 ]
Protection against electric shock through protective extra-low voltage (PELV):
Warning
Danger of electric shock
• Only use PELV circuits in accordance with IEC/E N 60204-1 (protective
extra-lo w voltage, PELV) for the electrical power supply.
Also observe the general requirements for PELV circuits as per
IEC/EN 60204-1.
• Only use voltage sources which guarantee reliable electrical isolation of the
operating voltage in ac c ordance with I EC/EN 60204-1.
The use of PE LV circuits ensures protection from electric shock (protection from
direct and indirect contact) in accordance with IEC/EN 60204-1 (Electrical equip-
ment of machines, General requirements). A 24 V power supply unit used in th e
system must satisfy the requirements of EN 60204-1 for DC power supply (beha-
viour during power interruptions, etc.).
