Siemens SINAMICS S220

Procedure
The holding brake requires a typical voltage of 24 V ±10%. Proceed as follows to determine the
input voltage of the Motor Module that matches the holding brake:
1. Take the holding brake voltage and its tolerance from the motor technical data.
– Take into account possible voltage drops in the Motor Module and along the supply cable.
Use a Control Supply Module or a controlled DC power supply whose setpoint is set to at
least 26V.
– Note that there are holding brakes that close again when the maximum voltage is
exceeded.
2. Check the permissible cable length using the following diagrams.
