(7) Positioning Start (CSTR): Used in Position/Simplified Direct Value Mode,
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.
Whether if the target position with the specified position No. is used or the setting using the PLC's
target position register is used, depends on the Control Signal b11: “Position/Simplified Direct Value
Change-Over (PMOD) Signal”.
x
PMOD = OFF: Target position data for the specified position No. is used.
x PMOD = ON: Value for the target position set using the PLC's target position register is used.
When this signal is issued in the condition where the homing operation has not performed at all after
the power injection (HEND signal OFF), the positioning to the target position is performed after the
homing operation is performed automatically.
Turn “OFF” this signal after confirming that the Positioning Completion Signal (PEND) signal has been
turned “OFF”.
(8) Positioning Command (DSTR): Used in Half Direct Value Mode or Full Direct Value
Mode,
This signal is processed at the startup (ON edge) and the positioning to the target position input in the
PLC's target position register is performed. When this signal is issued in the condition where the
homing operation has not performed at all after the power injection (HEND signal OFF), an alarm is
issued (Operation Cancellation Level).
Turn “OFF” this signal after confirming that the Positioning Completion Signal (PEND) signal has been
turned “OFF”.
(9) Under Movement Signal (MOVE),
This signal is turned ON while the actuator's slider or rod is moving (including the pressing or jog
operation after the homing operation).
After the completion of the positioning, homing or pressing operation, or during the pause condition, this
signal is turned “OFF”.
