Infeed At Reversal Point 1 Or 2 - Siemens SINUMERIK 840D sl Function Manual

Program code
M30
Example 2: changing reversal positions
For motion-synchronous actions, the reversal positions $$AA_OSCILL_REVERSE_POS are
used at the interpolator level. If the associated setting data change, then the modified values
are active in the program.

12.3.1

Infeed at reversal point 1 or 2

Function
As long as the oscillation axis has not reached the reversal point, the infeed axis does not
move.
Application
Direct infeed in reversal point
Programming
Reversal point 1
WHENEVER $AA_IM[Z] <> $SA_OSCILL_REVERSE_POS1[Z]
DO $AA_OVR[X] = 0 $AA_OVR[Z] = 100
Reversal point 2
WHENEVER $AA_IM[Z] <> $SA_OSCILL_REVERSE_POS2[Z]
DO $AA_OVR[X] = 0 $AA_OVR[Z] = 100
