Oscillation reversal points
The current offsets must be taken into account when oscillation positions are defined:
● Absolute specification
"OSP1[Z]=<value>"
Position of reversal point = sum of offsets + programmed value
● Relative specification
"OSP1[Z]=IC(<value>)"
Position of reversal point = reversal point 1 + programmed value
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, you must enable this axis 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).
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.
3.18.2 Oscillation controlled by synchronized actions (OSCILL)
With this mode of oscillation, an infeed motion may only be executed at the reversal points or
within defined reversal areas.
Depending on requirements, the oscillation movement can be
● Continued or
● Stopped until the infeed has finished executing.
Syntax
1. Define parameters for oscillation
2. Define motion-synchronous actions
3. Assign axes, define infeed
