the flag with index 0 is
1,
set the axial override of infeed axis X to 0% in order to
inhibit premature infeed (oscillating axis has not yet
left reversal area 2 but infeed axis is ready for a new
infeed)
set the axial override of oscillating axis to 100% (this
cancels the 2nd synchronized action).
