Comment
the current position of the oscillating axis in the
Machine Coordinate System
the start of reversal area 2
set the axial override of the feed axis
to 0%
set the marker with index 0 to value 0
the current position of the oscillating axis in the
Machine Coordinate System
reversal position 2
set the axial override of the oscillating axis
to 0%
the distance-to-go of the partial infeed is
0,
set the marker with index 0 to value 1
the flag with index 0 is
1,
set the axial override of the infeed axis to 0%
to prevent a new premature infeed
(oscillation axis has not yet exited the reversal point
range 2,
but the infeed axis is ready for a
new infeed)
set the axial override of the oscillation axis to 100%
(this cancels the 2nd synchronized action)
; Start the axes
The oscillating axis Z is assigned axis X as
an infeed axis
Axis X should travel to end position 5 in
increments of 1
