Name of oscillating axis
Activate/deactivate oscillation
Value: 1 Switch oscillation on
0 Switch oscillation off
Define position of reversal point 1
Define position of reversal point 2
Note:
If incremental movement is active, the position will be calculated incrementally
to the last corresponding reversal position programmed in the NC program.
Define stopping time in reversal point 1 in [s]
Define stopping time in reversal point 2 in [s]
: -2 Interpolation continues without wait for exact stop
<value>
-1 Wait for exact stop coarse
0 Wait for exact stop fine
>0 Wait for exact stop fine and then wait for specified stopping
time
Note:
The unit for the stopping time is identical to that of the
stopping time programmed with
Define feedrate
The feedrate is the defined feedrate of the positioning axis. If no feedrate is
defined, the value stored in the machine data applies.
Specify setting and reset options
Option values 0 to 3 encrypt the behavior at the reversal points on deactivation.
One of the variants from 0 to 3 can be selected. The remaining settings can be
combined at will with the selected variant. Multiple options are appended with
plus characters (+).
: 0 Stop at next reversal point on deactivation of oscillation
<value>
(default)
Note:
Only possible if values 1 and 2 are reset.
1 When the oscillation is deactivated, stop at reversal point 1
2 When the oscillation is deactivated, stop at reversal point 2
3 When the oscillation is deactivated, do not approach
reversal point if no spark-out strokes are programmed
4 Approach end position after spark-out
8 If oscillation is canceled by deletion of distance-to-go,
sparking-out strokes will then need to be executed and the
end position approached if necessary.
16 If oscillation is canceled by deletion of distance-to-go, the
corresponding reversal point will need to be approached as
is the case with shutdown.
32 New feed is only active after the next reversal point
