DBX6.2 Delete distance­to­go (channel­specific)
Edge evaluation: no
Signal state 1 or Delete distance­to­go (channel­specific):
edge change 0 → 1
IS "Delete distance­to­go (channel­specific)" for path axes is only active in AUTOMATIC mode.
The rising edge of the interface signal is only effective for the axes involved in the geometry
grouping. These are also stopped with a ramp stop and their distance­to­go deleted (setpoint -
actual value difference). Any remaining following error is not removed. The next program block is
then started.
IS "Delete distance­to­go (channel­specific)" is therefore ignored by positioning axes.
Note:
IS "Delete distance­to­go" does not influence the running dwell time in a program block with dwell
time.
