Po ssible solution
Selection of SLP in the converter; inhibits the
range that is not permitted.
The selection of SP in the converter enables you
to transfer a safe position (i.e. absolute or relative
position) to the higher-level controller via
PROFIsafe.
The diagnostic function "Safe Brake Test SBT"
detects whether a brake is achieving the required
braking effect.
The "Safe gearbox stage switchover" function
ensures safe switchover between the gearbox
stages.
