Part 3 Positioner Mode
„ Axis 1 home return complete (HEND1)
This signal is OFF while the power is input. It will turn ON at the following timings:
[1] The home-return operation has completed in connection with the first movement command issued
with the start signal.
[2] The home-return operation has completed following an input of the home return signal.
Once this signal turns ON, it will not turn OFF until the input power is cut off or the axis 1 home return
signal (HOME1) is input again.
„ Axis 2 home return complete (HEND2)
This signal is OFF while the power is input. It will turn ON at the following timings:
[1] The home-return operation has completed in connection with the first axis 2 movement command
issued with the start signal.
[2] The home-return operation of axis 2 has completed following an input of the axis 2 home return
signal (HOME2).
Once this signal turns ON, it will not turn OFF until the input power is cut off or the axis 2 home return
signal (HOME2) is input again.
„ Alarm (*ALM)
This signal remains ON while the controller is normal, and will turn OFF if an alarm occurs.
This signal will turn OFF when an error of operation-cancellation level or higher generates.
Program the PLC so that it will monitor this signal and implement appropriate safety measures to protect
the entire system when the signal turns OFF.
For details on alarms, refer to Appendix “ Error Level Management” and “ Error List.”
„ Ready (RDY)
This signal will turn ON when the initialization has completed successfully after the main power was input,
and the controller enters the mode where it can control the actuator.
This signal will turn OFF when an error of cold level or higher generates.
Use this signal as a condition to start control on the PLC side.
„ Servo ON output 1 (SVON1)
This signal will turn ON when the servo for axis 1 turns on. Issue a movement command after the servo
ON output signal has turned ON.
„ Servo ON output 2 (SVON2)
This signal will turn ON when the servo for axis 2 turns on. Issue a movement command after the servo
ON output signal has turned ON.
