(7) Positioning start (CSTR): Used in the position/simple direct mode PLC output signal
This command is processed at the leading (ON) edge of the signal, upon which the actuator moves to the position
set by the target position corresponding to the specified position or the PLC’s target position.
Whether to use the target position corresponding to the specified position number or PLC’s target position is
determined by the control signal b11 (position/simple direct switching (PMOD) signal).
x PMOD = OFF: Use the target position data under the specified position number
x PMOD = ON: Use the set value of the PLC’s target position
If this command is issued immediately after the power has been turned on, before home return is performed (=
when the HEND signal is OFF), the actuator will automatically perform home return operation and then move to
the target position.
Turn this signal OFF after confirming that the positioning complete signal (PEND) has turned OFF.
(8) Positioning command (DSTR): Used in the half direct mode and full direct mode PLC output signal
This command is processed at the leading (ON) edge of the signal, upon which the actuator moves to the target
position entered as the PLC’s target position (*). If this command is issued immediately after the power has been
turned on, before home return is performed (= when the HEND signal is OFF), an alarm (operation-cancellation
alarm) will occur.
Turn this signal OFF after confirming that the positioning complete signal (PEND) has turned OFF.
(9) Moving signal (MOVE) PLC input signal
This signal turns ON while the actuator slider or rod is moving (including cases where the actuator is performing
home return operation, push-motion operation or jog operation).
The signal turns OFF after the positioning, home return or push-motion operation is completed or while the
operation is paused.
