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
Define end position (in workpiece coordinate system) to be approached after
deactivation of oscillation.
Note:
When programming
OSE
Define start position (in workpiece coordinate system) to be approached prior
to activation of oscillation.
The start position is approached before reversal point 1. If the start position
coincides with reversal position 1, reversal position 2 is approached next. No
stopping time applies when the start position is reached, even if this position
coincides with reversal position 1; instead, the axis waits for the exact stop fine
signal. Any exact stop condition configured is fulfilled.
Note:
Bit 9 in setting data SD43770 $SA_OSCILL_CTRL_MASK must be set to
initiate an approach to the start position.
option 4 becomes effective implicitly for
