When the monitoring function 2b [SS2, standstill-prioritized with NC-controlled
transition (based on actual velocity)] has been configured, the axis is deceler-
ated in an NC-controlled way when SS2 is selected; i.e. the higher-level control
unit decelerates the drive via the command value system.
To monitor the standstill process, the transition function "Safe stop 2 (SS2)"
