(Note 1) The completion position No. output is set to 0 during movement of the actuator.
Caution:
(1) Set the period taken from entering position No. to turning CSTR ON to 6ms or larger. In spite of
6ms timer process in the PLC, commands may be input to the controller concurrently to cause
positioning to another position. Take the scanning time in the PLC into account to set a period as
2 to 4 times as the scanning time. Set the value similarly if the PLC reads the complete position.
(2) At the completion of positioning, positioning complete signal PEND is not turned ON if start
signal SCTR remains ON. If this occurs, turn CSTR OFF then PEND is turned ON immediately.
Therefore, create the sequence program so that turning PEND ON makes CSTR turned OFF
and the PLC waits for the state in which PEND is turned ON.
(3) At the positioning to the position same as that specified in the stop (complete) position number,
PEND is turned OFF once but moving signal MOVE is not turned ON.
Therefore, use PEND to turn CSTR OFF.
(4) MOVE turns on at the same time as PEND turns OFF, and turns OFF when a movement
command is finished or PEND is turned ON. Therefore, when the positioning band setting is
wide, the signal may turn OFF even in the actuator operation, and may turn off prior to PEND if
the positioning band setting is narrow.
