Switching over SLS levels

Overview
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.
The inverter monitors the motor as it brakes using
the SBR (Safe Brake Ramp) function.
Switching over SLS levels is only possible via PROFIsafe with control word 1.
The inverter signals the active SLS level via PROFIsafe to the higher-level control.
