the 5 rpm and has no effect to the trip limit scaling.

The Variable SLS function uses SAR1 parameters to monitor and/or define the
deceleration ramp (Variable SLS with ramp monitoring). See section
Configuring SAR
on page 361 .
The FSO module activates the STO function if the motor speed hits a ramp
monitoring limit during the deceleration ramp (Variable SLS with ramp monitoring).
See section
Configuring STO on page 331 .
The FSO module activates the SSE function if the motor speed hits a trip limit. See
