Note
Removal of the "Controller enable" and "Pulse enable" during traversing results in a rapid stop
of the axis and a reset alarm.
Interruption of a traversing motion
When a stop command is issued, the distance-to-go is saved and the handwheel pulses are
collected. When the stop condition no longer applies, the resulting distance is traversed.
Abort of a traversing motion
When a stop command is issued, the distance-to-go is deleted and the handwheel pulses are
ignored (i.e. not collected) until the stop condition no longer applies.
