Comment
the beginning of reversal range 2
(here: reversal point 2 -6),
set the axial override of the infeed axis to 0%.
set the marker with index 2 to value 0
(Reset marker 2)
the current position of the oscillating axis in the
Machine Coordinate System
reversal position 1,
set the axial override of the oscillation axis to 0%
Set the axial override of the infeed axis to
100% (so that the previous synchronized action
is cancelled!)
the distance-to-go of the partial infeed is
0,
set the marker with index 2 to value 1
set the marker with index 1 to value 1
the flag with index 2 is
1,
Set the axial override of the infeed axis to
0%, this prevents a premature infeed
(oscillation axis has not exited the
reversal point 1).
the flag with index 1 is
1,
Set the axial override of the infeed axis to
0%, this prevents a premature infeed
(oscillation axis has not exited the
reversal point range 2).
Set the axial override of the infeed axis to
100% ('Start' oscillation)
