the flag with index 1 is
1,
set the axial override of the infeed axis to 0%; this
prevents premature infeed (oscillation axis has not left
reversal range 2 yet)
set the axial override of the oscillation axis to 100%
('Start' oscillation)
reversal position 1,
set the axial override of the oscillation axis to 100%
set the axial override of infeed axis Z to 0% (this
cancels the second synchronous action once only!).
Sequences of oscillation movements and infeed, example 1
; assign axis X to the oscillation axis Z as
oscillation axis, which has to infeed up to end
position 5 in steps of 1 and the sum of all
partial distances must add up to the end
position
