Function
Deactivation at defined reversal
point
Deactivation with specific
number of sparking-out strokes
Deactivation with sparking-out
strokes and defined end position
(optional)
Deactivation without sparking-
out strokes, but with defined end
position (optional)
NC language
The NC programming language allows asynchronous oscillation to be controlled from the
part program. The following functions allow asynchronous oscillation to be activated and
controlled as a function of NC program execution.
Note
If the setting data is directly written in the part program, then the data change takes effect
prematurely with respect to processing of the part program (at the preprocessing time). It is
possible to re-synchronize the part program and the oscillation function commands by
means of a preprocessing stop (

1) Activate, deactivate oscillation:
● OS[oscillation axis] = 1; Activate oscillation for oscillation axis
● OS[oscillation axis] = 0; Deactivate oscillation for oscillation axis
Note
Every axis may be used as an oscillation axis.

Explanation
The oscillation movement is
stopped at the appropriate
reversal point
After the appropriate reversal
point is reached, the number of
sparking-out strokes specified in
the command are processed.
After the appropriate reversal
point is reached, the number of
sparking-out strokes specified in
the command are processed,
followed by approach to
specified end position.
After the appropriate reversal
point is reached, the axis is
traversed to the specified end
position.
