(6) Home return (HOME) [PLC output signal]
Home return complete (HEND) [PLC input signal]
Home return in progress (GHMS) [PLC input signal]
When the HOME signal is turned ON, the HOME command will be processed at the leading (ON) edge of the
signal and home-return operation will be performed automatically. The GHMS signal turns ON while the home
return is in progress.
Once the home return has completed, the HEND signal turns ON and the GHMS signal turns OFF.
Program the controller so that the HOME signal will turn OFF after the HEND signal turns ON. Once it is turned
ON, the HEND signal will not turn OFF until the power is turned off or a HOME signal is input again.
After a home return has been performed once, another home return can be performed by turning ON the HOME
signal.
Caution: In the remote I/O mode, remote I/O mode 2 or position/simple direct mode, issuing a
positioning command to a given position following the power on, without performing a
home return first, will cause the actuator to automatically return home and then perform the
positioning. Take note that this applies only to the first positioning command following the
power on.
Exercise caution that in the half direct mode or full direct mode, issuing a positioning
command to a given position following the power on, without performing a home return
first, will generate an alarm (“Error Code 83: Alarm home ABS (absolute position move
command when home return is not yet completed)” (operation-reset alarm).
