Sls With Braking Ramp Monitoring - Siemens Sinamics G120 Function Manual

Operation
6.6 Safely Limited Speed (SLS)
6.6.2.1

SLS with braking ramp monitoring

If the machine control selects the SLS safety function via a fail-safe digital input or via
PROFIsafe communication, then the motor behaves differently depending on the absolute
value of the load speed. These two scenarios are described below.
Scenario 1: The absolute value of the load speed is less than the setpoint speed limit.
Function
1. The motor continues to follow the speed setpoint.
2. The inverter monitors the speed after the delay time has expired.
