5. Enable oscillation movement (see Section "Oscillation movement restarting (Page 711)").
6. Do not start partial infeed too early (see Section "Do not start partial infeed too early
(Page 712)").

Programming
Before the motion block that contains the assignment between the infeed and the oscillating
axis (see Section "Assignment of oscillation and infeed axes OSCILL (Page 713)"), the infeed
definition (POSP) and the motion-synchronous actions, the parameters for the oscillation must
first be defined (see Section "Influences on asynchronous oscillation (Page 695)"):
The oscillation axis is enabled via a WAITP [oscillation axis] (see MD30552
$MA_AUTO_GET_TYPE), allowing the oscillation parameters to be transferred, i.e. into the
setting data, simultaneously. The symbolic names, e.g. SA43700 $SA_REVERSE_POS1 can
then be used to program the motion-synchronous actions.
Note
For motion-synchronous actions with $SA_REVERSE_POS values, the comparison values at
the time of interpretation are valid. If setting data is changed afterwards, this has no effect.
For motion-synchronous actions with $AA_REVERSE_POS values, the comparison values
within the interpoltation are valid. This ensures a reaction to the modified reversal positions.
