Stop oscillation motion at reversal point
The oscillation axis is stopped at the reversal point,
the infeed motion starts at the same time.
The oscillating motion is continued when the infeed
movement is complete.
This synchronized action can also be used to start
the infeed movement if this has been stopped by a
previous synchronized action which is still active.
The following instructions are used subject to the
above assumptions:
Reversal point 1:
WHENEVER $SA_IM[Z]==$SA_OSCILL_REVERSE_POS1[Z]DO $AA_OVR[Z]=0 ->
-> $AA_OVR[X] = 100
Whenever
equal to
then
and
Reversal point 2:
WHENEVER $SA_IM[Z] ==$SA_OSCILL_REVERSE_POS2[Z]DO $AA_OVR[Z]= 0 ->
-> $AA_OVR[X]=100
Whenever
equal to
then

the current position of oscillating axis in the MCS is
the position of reversal point 1
set the axial override of the oscillating axis to 0%
set the axial override of the infeed axis to 100%.
the current position of oscillating axis in the MCS is
the position of reversal point 2
set the axial override of the oscillating axis to 0%
set the axial override of the infeed axis to 100%.
