Motor holding brake
The motor holding brake holds the motor in position when it is switched off. If the setting is
correct, the motor will produce an electrical holding torque before the inverter opens the
brake. The inverter does not close the motor holding brake until the motor is at a standstill.
Connecting a motor holding brake
You can use any inverter digital output to control the motor holding brake.
If the current or voltage rating of the digital output is not sufficient, then you must control the
motor holding brake through a coupling relay.

To define which of the digital outputs of the inverter is used to control the motor holding
brake, you must interconnect the corresponding digital output with the brake control signal:
● Digital output DO 0: p0730 = 52.12
● Digital output DO 1: p0731 = 52.12
