(19) Operation mode (RMOD) PLC output signal
Operation mode status (RMDS) PLC input signal
A different operation mode is selected as follows based on the RMOD signal and the MODE switch on the front
side of the controller.
Whether the current mode is AUTO or MANU can be checked using the RMDS signal.
RMOD signal and mode switch combinations, and corresponding operation modes, are shown below.
Controller’s MODE switch
in AUTO position
Controller’s MODE switch
in MANU position
RMOD signal OFF (AUTO
mode is specified)
AUTO mode
(RMDS=OFF)
MANU mode
(RMDS=ON)
RMOD signal ON (MANU
mode is specified)
MANU mode
(RMDS=ON) MANU mode
(RMDS=ON)
(Note) Operation from the PLC is not supported in the MANU mode.
(20) Position/simple direct switching (PMOD) PLC output signal
This signal switches between the mode where a value registered in the controller’s position table is used as the
target position for movement, and the mode where the PLC’s target position address is used.
PMOD = OFF: Use the position table
PMOD = ON: Use the value of the PLC’s target position address
(21) Push specification (PUSH) PLC output signal
When a move command is issued after turning this signal ON, the actuator will perform push-motion operation.
If this signal is turned OFF, the actuator will perform normal positioning operation.
(Refer to (2), “Operation in the half direct mode” under 3.8 “Operation”.)
(22) Push direction specification (DIR) PLC output signal
This signal specifies the direction in which the actuator will push the load.
When this signal is turned OFF, the actuator will push the load toward the position obtained by subtracting the
positioning band from the target position.
When this signal is turned ON, the actuator will push the load toward the position obtained by adding the
positioning band to the target position.
This signal is invalid during normal positioning operation.
(For the setting timing of this signal, refer to (2), “Operation in the half direct mode” under 3.8. “Operation”.)
