5. I/O Signal Control and Signal Functions
„ Pause (*STP)
When this signal turns OFF while the actuator is moving, the actuator will decelerate to a stop.
The remaining movement is retained and will be resumed when the signal is turned ON again.
To abort the movement command, turn ON the alarm reset signal while this signal is OFF to cancel the
remaining movement.
The *STP signal can be used for the following purposes:
[1] Provide a low-level safety measure to stop the axis while the servo is ON, such as a sensor that detects a
person approaching the system
[2] Prevent contact with other equipment
[3] Perform positioning based on sensor or LS detection
(Note) If the *STP signal is input while the actuator is performing home return, the movement command will be
retained if the actuator is yet to contact a mechanical end. If the signal is input after the actuator has
reversed upon contacting a mechanical end, home return will be performed again from the beginning.
„ Home return (HOME)
The controller will start home return operation upon detection of an OFF o ON edge of this signal.
When the home return is complete, the HEND signal will be output. The HOME signal can be input as many
times as required.
„ Servo ON (SON)
The servo remains ON while this signal is ON.
When the power is turned on, make sure this signal will turn ON after the safety of the entire equipment is
ensured, i.e., after a confirmation that the actuator will not contact surrounding equipment.
If the SON signal need not be used in view of the nature of the equipment, you can disable the signal using
parameter No. 21.
When this signal is disabled, the servo will turn on automatically after the power is turned on.
The factory setting is to enable the SON signal.
„ Alarm reset (RES)
This signal provides two functions.
[1] Reset the alarm output signal (*ALM) that turned OFF due to an alarm
If an alarm has generated, turn ON this signal after confirming the nature of the alarm.
The controller will reset the alarm upon detection of a rise edge of the RES signal.
(Note) Certain alarms cannot be reset by the RES signal. For details, refer to 10, “Troubleshooting.”
[2] Cancel the remaining movement when the pause signal is OFF
This function is used when the remaining movement must be cancelled to allow for incremental moves
(movements at a constant increment) from the position where the actuator stopped following a sensor
detection.
