3.9.1 Judgment Method of End Position
Although completion judgment is based on the applicable count managed by the PLC, the zone output signal
can be used additionally to double-check the completion of movement.
Program the PLC so that the ON/OFF status of the zone output signal is checked when positioning is completed,
and if the signal is OFF, the applicable position will be determined as the last load position.
If the count in the PLC does not match the zone output signal status, signal timings may not be synchronized.
