Siemens SINAMICS V20 Operating Instructions Manual page 101

Connecting the motor holding brake
The motor holding brake can be connected to the inverter via digital outputs (DO1/DO2). An
additional relay is also required to allow the digital output to enable or disable the motor
holding brake.
Potentially hazardous load
If the inverter controls the motor holding brake, then a commissioning may not be carried
out for potentially hazardous loads (e.g. suspended loads for crane applications) unless the
load has been secured.
It is not permissible to use the motor holding brake as operating brake. The reason for this
is that generally it is only designed for a limited number of emergency braking operations.
