Perform home-return operation by following the procedure explained below.
* Before commencing the procedure, confirm that the ready output signal and alarm output signal are
ON.
[1] Turn ON the servo ON input signal.
[2] Confirm that the servo-ON status output signal is ON.
[3] Turn ON the home-return input signal.
[4] Confirm that the positioning complete output signal is OFF.
[5] Turn OFF the home-return input signal.
[6] Confirm that the home-return complete output signal is ON. Home return is now completed.
*Pause and *cancellation inputs are contact-B input signals (always ON), so keep these signals ON while
home return is in progress.
To initiate home return using the home-return signal input, the servo ON input signal must be ON. These
operation commands will not be accepted if the servo ON input signal is OFF. Note, however, that only the
commands will be ignored and no error will generate.
