11.1 Asynchronous oscillation (OS, OSP1, OSP2, OST1, OST2, OSCTRL, OSNSC, OSE, OSB)
Oscillation reversal points
The current offsets must be taken into account when oscillation positions are defined:
● Absolute specification
● Relative specification
Example:
Program code
N10 OSP1[Z]=100 OSP2[Z]=110
...
...
N40 OSP1[Z]=IC(3)
WAITP
If oscillation is to be performed with a geometry axis, this axis must be enabled for oscillation
with WAITP.
When oscillation has finished, WAITP is used to enter the oscillating axis as a positioning
axis again, so that normal use can resume.
Oscillation with motion-synchronous actions and stopping times
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 motion sequence (OSCTRL).
by the feed override.
An oscillation stroke may then be executed before the sparking-out strokes are started or the
end position approached.
this is not in fact the case.

OSP1[Z]=<value>
Position of reversal point = sum of offsets + programmed value
OSP1[Z]=IC(<value>)
Position of reversal point = reversal point 1 + programmed value
Although it appears as if the deactivation response has changed,
This dynamic response can be influenced
