Siemens CU240B-2 Function Manual

6.6.3.2 SLS without braking ramp monitoring
Function
When you switch from a higher to a lower speed monitoring level (SLS level), the following
takes place:
1. The inverter brakes the motor.
2. Once the delay time has expired, the inverter monitors the speed using the lower speed
monitoring level.
When you switch from one of the lower monitoring level to a higher speed monitoring level,
then the inverter immediately monitors the speed with the higher SLS level.
