Direction of motion for trigger output:
If the start and stop thresholds are active in "Position Distance" trigger mode
(start threshold ≠
stop threshold), the value of the
Pos. Distance Trig. Single Direction
parameter (ID 0x18000300)
determines the direction of motion for trigger output:
0 (default setting) = Trigger is generated whenever the position is within the range
defined by the start/stop thresholds. Trigger output is independent of the current
direction of motion, i.e. continues when the motion direction is reversed before the
axis position has reached the stop threshold (Figure 22).
1 = Trigger is generated only when the position is within the range defined by the
start/stop thresholds
and
when the axis moves in the direction determined by the
start/stop thresholds (Figure 23)
If start and stop thresholds are not active (start threshold = stop threshold), the
Pos. Distance Trig.
Single Direction
parameter has no effect.
