Switching over SLS levels
When SLS is active, you can switch between four different speed levels via PROFIsafe.
The drive response when switching over to a lower SLS level depends on whether you have
selected SLS with or without braking ramp monitoring.
With braking ramp monitoring
The inverter monitors the motor as it brakes using
the SBR (Safe Brake Ramp) function.
