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
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
