Wiring diagrams of the brake control for BK.. or BZ.D brake
In every application, the BK holding brake can be controlled via the BMV brake relay
or a customer relay with varistor overvoltage protection.
If the system complies with the specifications for direct brake control, then a BK..
brake can also be controlled directly via the brake output of a servo inverter by
SEW‑EURODRIVE.
