StandstillSignal tags (positioning axis/synchronous axis)
The tag structure <TO>.StandstillSignal.<tag name> contains the configuration for the
standstill signal.
If the actual velocity value is below the velocity threshold, and does not exceed it during the
minimum dwell time, then the standstill signal <TO>.StatusWord.X7 (Standstill) is set.
