The deceleration check time required during rapid traverse is the longest rapid traverse
deceleration check time of all axes. This check time is determined by the rapid traverse
acceleration/deceleration mode and rapid traverse acceleration/deceleration time constant of
simultaneously commanded axes.
The deceleration check time required during cutting feed is determined in the same manner. It
is the longest rapid traverse deceleration check time on all axes. This check time is
determined by the cutting feed acceleration/deceleration mode and cutting feed acceleration/
deceleration time constant of simultaneously commanded axes.
