The unit for the stopping time is identical to the stopping time programmed with G4.
Example of an oscillating axis that should oscillate between two reversal points
The oscillation axis Z must oscillate between 10 and 100. Approach reversal point 1 with
exact stop fine, reversal point 2 with exact stop coarse. Machining is performed with
feedrate 250 for the oscillating axis. Three sparking-out strokes must be executed at the end
of the machining operation followed by approach by oscillation axis to end position 200. The
feedrate for the infeed axis is 1, end of the infeed in X direction is at 15.
