The following table explains the motional behavior in the exact stop range or at the reversal
point, depending on the stop time input.

Deactivate oscillation
One of the following options can be set for termination of the oscillation movement when
oscillation mode is deactivated:
● Termination of oscillation movement at the next reversal point
● Termination of oscillation movement at reversal point 1
● Termination of oscillation movement at reversal point 2
Following this termination process, sparking-out strokes are processed and an end position
approached if programmed.
On switchover from asynchronous oscillation to spark-out and during spark-out, the
response at the reversal point regarding exact stop corresponds to the response determined
by the stop time programmed for the appropriate reversal point. A sparking-out stroke is the
motion to the other reversal point and back (see the table below):
Note
Oscillation with motion-synchronous actions and stop times "OST1/OST2"
Once the set stop times have expired, the internal block change is executed during
oscillation (indicated by the new distances-to-go of the axes). The deactivation function is
checked when the block changes. The deactivation function is defined according to the
control setting for the motional sequence "OSCTRL".
This dynamic response can be influenced by the feed override.
An oscillation stroke may then be executed before the sparking-out strokes are started or the
end position approached.
Although it appears as if the deactivation response has changed, this is not in fact the case.
