Defining the sequence of motions, OSCTRL
The control settings for the movement are set with enable and reset options.
OSCTRL[oscillating axis] = (set-option, reset-option)
The set options are defined as follows (the reset options deselect the settings):
Reset options
These options are deactivated (only if they have previously been activated as setting
options).
Setting options
These options are switched over. When OSE (end position) is programmed, option 4 is
implicitly activated.

Several options are appended with plus characters.
Example:
The oscillating motion for the Z axis should stop at the reversal point 1 when switched off.
Where
• an end position is approached,
• a changed feed acts immediately and should immediately stop the axis after the deletion
OSCTRL[Z] = (1+4,16+32+64)

Meaning
When the oscillation is deactivated, stop at the next reversal point (default)
only possible by resetting values 1 and 2
When the oscillation is deactivated, stop at reversal point 1
When the oscillation is deactivated, stop at reversal point 2
When the oscillation is deactivated, do not approach reversal point if no
spark-out strokes are programmed
Approach end position after spark-out
If the oscillation movement is canceled by deletion of the distance-to-go:
then execute spark-out strokes and approach end position if appropriate
If the oscillation movement is canceled by deletion of the distance-to-go:
reversal position is approached as with deactivation
New feed is only active after the next reversal point
FA equal to 0, FA = 0: Path overlay is active
FA not equal to 0, FA <> 0: Speed overlay is active
For rotary axis DC (shortest path)
0=The sparking out stroke is a dual stroke.(default) 1=single stroke.
