SLS without braking ramp monitoring

Selecting and deselecting SLS
If the machine control selects the SLS safety function via a safety input or via the PROFIsafe
safe 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.
