Restart oscillation movement
This synchronized action is used to continue the
oscillating movement when the partial infeed
movement is complete.
The following instructions are used subject to the
above assumptions:
WHENEVER $AA_DTEPW[X]==0 DO $AA_OVR[Z]= 100
Whenever
equal to
then
the distance-to-go for the partial infeed on infeed axis X in the WCS
zero
set the axial override of the oscillating axis to 100%.
