Explanation of I/O Signal Functions
The table below explains the functions assigned to the respective I/O signals of the controller.
Since the signals that can be used vary depending on the controller type and settings, check the signal table for each
controller to confirm the available functions.
n Controller Functions by Type
Category
Abbreviation
CSTR
PTP strobe signal (start signal)
Signal name
Input this signal to cause the actuator to start moving to the position set by the
command position number signal.
PC1~PC256 Command position number signal
This signal is used to input a target position number (binary input).
Function description
BKRL Brake forced-release signal
This signal forcibly releases the brake.
RMOD Running mode switching signal
This signal can switch the running mode when the MODE switch on the controller is
set to AUTO (AUTO when this signal is OFF, or MANU when the signal is ON).
* STP Pause signal
Turning this signal OFF causes the moving actuator to decelerate to a stop. The actuator
will resume the remaining movement if the signal is turned OFF during the pause.
MODE Teaching mode signal
Turning this signal ON switches the controller to the teaching mode (provided that
CSTR, JOG+ and JOG- are all OFF and the actuator is not moving).
RES Reset signal
Turning this signal ON resets the alarms that are present. If this signal is turned ON
while the actuator is paused (*STP is OFF), the remaining movement can be cancelled.
SON Servo ON signal
The servo remains on while this signal is ON, or off while the signal is OFF.
JISL Jog/inching switching signal
The actuator can be jogged with JOG+ and JOG- while this signal is OFF. The
actuator performs inching operation with JOG+ and JOG- while this signal is ON.
JOG+ JOG– ------
----
ST0~ST6 Start position command
Turning this signal ON in the solenoid valve mode causes the actuator to move to the
specified position. (Start signal is not required.)
TL Torque limit selection signal
While this signal is ON, torque is limited by the value set by a parameter. The TLR
signal turns ON if torque has reached the specified value.
DCLR Deviation counter clear signal
The position deviation counter is continuously cleared while this signal is ON.
PEND/INP Position complete signal
This signal turns ON when the actuator has entered the positioning band after
movement. If the actuator has exceeded the positioning band, PEND does not turn
OFF, but INP does. PEND and INP can be swapped using a parameter.
PWRT Teaching signal
In the teaching mode, specify a desired position number and then turn this signal ON
for at least 20 ms to write the current position under the specified position number.
HOME Home return signal
Turning this signal ON performs home-return operation.
Input
Output
PM1~PM256 Completed position number signal
This signal is used to output the position number achieved at completion of
positioning (binary output).
HEND Home return complete signal
This signal turns ON upon completion of home return.
ZONE1 Zone signal
This signal turns ON when the current actuator position has entered the range
specified by parameters.
PZONE Position zone signal
This signal turns ON when the current actuator position has entered the range
specified by position data during position movement. PZONE can be used together
with ZONE1, but PZONE is valid only during movement to a specified position.
RMDS Running mode status signal
This signal is used to output the running mode status.
* ALM Controller alarm status signal
This signal remains ON while the controller is normal, and turns OFF if an alarm has
generated.
SV Servo ON status signal
* EMGS Emergency stop status signal
This signal remains ON while the controller is not in the emergency stop mode, and
turns OFF once an emergency stop has been actuated.
MODES Mode status signal
This signal turns ON when the controller has switched to the teaching mode via
MODE signal input. It turns OFF upon returning to the normal mode.
WEND Write complete signal
This signal remains OFF after the controller has switched to the teaching mode. It
turns ON upon completion of data write using the PWRT signal. If the PWRT signal is
turned OFF, this signal also turns OFF.
PE0~PE6 Current position number signal
This signal turns ON after the controller has completed moving to the target position
in the solenoid valve mode.
TLR Torque limiting signal
This signal turns ON once the motor torque has reached the specified value in a
condition where torque is being limited by the TL signal.
LSO~LS2
TRQS
Limit switch output signal
---
Each signal turns ON when the current actuator position has entered the positioning band
before or after the target position. If the actuator has already completed home return, these
signals are output even before a movement command is issued or while the servo is OFF.
--------
MOVE Moving signal
This signal remains ON while the actuator is moving (including the periods during
home return and push-motion operation).
This signal remains ON while the servo is on.
