Brake control

Brakes are controlled via relay contact X22 on the inverter. It is not permitted to control them via other electronic devices or via controllers.

Upon of a motor with a brake, relay contact X22 (DOR-C; DOR-NO) is automatically parameterized to brake output and locked against subsequent manual changes if a motor with a brake in the drive train is configured. This functionality is supported with the MOVISUITE^® engineering software or with the CBG11A or CBG21A keypads.

As a result, a power contactor with DC 24 V coil voltage or a suitable brake rectifier from SEW‑EURODRIVE can be controlled directly. The brake is switched with this power contactor.

Direct switching of the brake via relay contact X22 (DOR-C, DOR-NO) is not permitted.
