Siemens SINAMICS G120C Function Manual

Selecting SS1 when the motor is rotating
Function
1. The higher-level control selects the SS1 function
2. The inverter brakes the motor with the OFF3 ramp-down time.
3. The inverter closes the motor holding brake once the motor is at a standstill.
4. If the standstill monitoring is undershot, or once the delay time has expired, the inverter
activates the STO function and controls the brake with the SBC function.
