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 G4.
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 (default)
<value>:
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 approach‐
ed if necessary.
16 If oscillation is canceled by deletion of distance-to-go, the corre‐
sponding reversal point will need to be approached as is the case
with shutdown.
32 New feed is only active after the next reversal point
64 FA equal to 0, FA = 0: Path overlay is active
FA not equal to 0, FA <> 0: Speed overlay is active
128 For rotary axis DC (shortest path)
256 The sparking-out stroke is a dual stroke (default). 1=Single stroke.
512 First approach start position
Define number of sparking-out strokes
