Note
(1) Stops and starts of spindle oscillation are executed with the level trigger for the spindle oscillation command signal, but
stops and starts of spindle oscillation are executed with the edge trigger for scenarios when emergency stop has been
executed. As spindle oscillation restarts from the stopped position, oscillation may not start from the same initial oscilla-
tion position.
