the axis will move by only the external
positioning run distance (10000
pulses) at latch signal input (external
positioning signal) during feed motion
execution. The positioning completion
signal IBC000D goes ON at the
completion of motion. If the latch
signal is not input, then the posiitioning
completion signal IBC000D goes ON
when absolute position 10000 is
reached.
