The brake outlet is internally equipped with an overvoltage protection circuit. This reduces
high voltage peaks that can occur when the brake is switched off and protects the electronic
outputs. An additional external protective circuit for the brake output is not required. The
brake output is short-circuit resistant. The following monitoring is also performed on the
brake outlet:
● Current flow only when the brake is switched on; monitors whether a consumer is
attached
● Wire breakage only when the brake is switched on
Note
The above-mentioned monitoring is possible only when the brake is directly attached to
the Motor Module without interface contactor.
