This signal is processed at the startup (ON edge) and the positioning is performed to the target
position with the specified position No. or set using the PLC’s target position register.
1) Once the start signal CSTR is turned ON, the actuator starts to accelerate following the
data in the specified position table to perform positioning at the target position.
2) Once the operation starts, the positioning complete signal PEND turns OFF. Turn OFF
CSTR Signal. If CSTR Signal is not turned OFF, output of complete position number cannot
be performed and the positioning complete signal would not turn ON when the positioning
is complete.
3) Once the positioning is complete, the number of positioning complete position is output in
the binary data by Complete Position No. PM1 to PM**, and the positioning complete signal
PEND is turned ON at the same time.
4) The moving signal MOVE turns ON at the same time as the operation starts, and turns OFF
once the positioning complete signal PEND turns ON or the movement command output
completes.
5) The positioning complete signal PEND turns ON once the remaining movement gets into
the range of the positioning band. PEND Signal will be kept ON once it is turned ON unless
the start signal CSTR is turned back ON, servo is turned OFF (Note 1) or the actuator is out of
the positioning band width range (Note 1) .
Note 1: It can be switched over with Parameter No. 39.
Note 1: The complete position number output becomes 0 during a movement.
Note 2: MOVE turns ON at the same time as PEND turns OFF, and turns OFF once the
command from a controller to the motor is finished. 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.
