Siemens SINAMICS G120C Function Manual

Scenario 2: The absolute value of the load speed is higher than the setpoint speed limit.
Function
1. The inverter brakes the motor.
2. The inverter monitors the speed after the delay time has expired.
3. If you deselect SLS, then the motor accelerates again up to the speed setpoint.
