4.3 Motor Module with external air cooling

A regulated DC power supply is required to operate motors with a built-in holding brake. The

voltage is supplied via the internal 24 V busbars. The voltage tolerances of the motor holding

brakes and the voltage drops of the connection cables must be taken into account.

The DC power supply should be set to 26 V. This ensures that the voltage supply for the

brake remains within the permissible range when the following conditions are fulfilled:

• Using Siemens three-phase motors

• Using Siemens MOTION-CONNECT power cables

• Motor cable lengths: max. 100 m

The DC link side covers are supplied as standard with the components; they can also be

ordered separately, if required (order no.: 6SL3162-5AA00-0AA0).
