(Page 73).
Note
Shielding
Attach the motor cable shield to the shield connection plate on the Motor Module using the
shield connection clamp supplied in the terminal kit. You can find more detailed information
in Chapters "Motor connector" (Page 73) and "Shielding and routing cables" (Page 123).

Motor holding brake connection
To ensure reliable opening of the motor holding brake, it requires a typical voltage of 24 V ±
10% at the motor connection. Refer to the data sheet of the motor for the motor holding
brake voltage and tolerance.
● Also take into account that voltage drops occur in the motor module and on the supply
cable.
● Use a Control Supply Module or a regulated DC power supply whose setpoint is set to at
least 26 V.
● Note that there are motor holding brakes that close again when the maximum voltage is
exceeded.
