Siemens SINUMERIK 804D sl Programming Manual

The following instructions are used subject to the above assumptions:
Reversal range 1:
WHENEVER $AA_IM[Z]<>$SA_OSCILL_RESERVE_POS1[Z] DO $AA_OVR[X]=0
$AA_OVR[Z]=100
Whenever the actual position of oscillating axis Z in MCS is greater or less than the position
reversal point 1, then set the axial override of the infeed axis X to 0% and the axial override of
the oscillating axis Z to 100%.
Reversal range 2:
For reversal point 2:
WHENEVER $AA_IM[Z]<>$SA_OSCILL_RESERVE_POS2[Z] DO $AA_OVR[X]=0
$AA_OVR[Z]=100
Whenever the actual position of oscillating axis Z in MCS is greater or less than the position
reversal point 2, then set the axial override of the infeed axis X to 0% and the axial override of
the oscillating axis Z to 100%.
Stop oscillation movement at the 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.
At the same time, this synchronized action can 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 range 1:
WHENEVER $SA_IM[Z]==$SA_OSCILL_RESERVE_POS1[Z] DO $AA_OVR[X]=0
$AA_OVR[Z]=100
Whenever the actual position of the oscillating axis in the MCS is the same as the reversal
position 1, then set the axial override of the oscillating axis to 0% and the axial override of the
infeed axis to 100%.
Reversal range 2:
WHENEVER $SA_IM[Z]==$SA_OSCILL_RESERVE_POS2[Z] DO $AA_OVR[X]=0
$AA_OVR[Z]=100
Whenever the actual position of the oscillating axis Z in the MCS is the same as the reversal
position 2, then set the axial override of the oscillating axis X to 0% and the axial override of
the infeed axis to 100%.
Online evaluation of reversal point
If there is a main run variable coded with $$ on the right of the comparison, then the two
variables are evaluated and compared with one another continuously in the IPO cycle.
