The circuit for protecting the brake against overvoltage is integrated in the Motor Module and does not need to be in-
stalled externally.
Motor holding brake connection
To ensure reliable opening of the motor holding brake, it requires a 24 V ± 10% voltage
supply at the motor connection. It must be taken into account that voltage dips can occur
along the supply cable.
● Use a Control Supply Module or a regulated DC power supply, whose setpoint is set to
26 V.
● Use supply cables with a minimum cross-section of 1.5 mm² and a maximum length of
100 m.
