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.

Figure 4-33 Connect the motor holding brake to digital output DO 0 of the inverter via interface relay
K1.
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
