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

Program code
OS[Z]=0
M30
Example 2: changing reversal positions
For the motion-synchronized actions, as reversal position, main run variable $
$AA_OSCILL_REVERSE_POSx is used. If the corresponding setting data change, then the
modified values are active in the program.

15.3.1

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]
