(8) Home return command (HOME)
Home return complete (HEND)
Home return operation is started at the leading edge of the HOME signal from “0” (OFF) to “1” (ON).
The HEND (home return complete) signal turns “1” (ON) when the home return is completed.
Turn the HOME signal “0” (OFF) after the HEND signal has turned “1” (ON). Once turned “1” (ON),
the HEND signal will not turn “0” (OFF) until the power is turned off or the HOME signal is input
again. This means that you can perform home return using the HOME signal as many times as
desired, even after the initial home return is completed.
Caution
1. With a positioner operation axis operated in the position number specification mode or command
specification mode, issuing a positioning command to a given position without performing home
return following the power on will cause the actuator to automatically return home and then
perform positioning, provided that it is the first positioning operation after the power on.
2. Take note that in any other mode, an alarm “Error code 83: ALARM HOME ABS (absolute
position movement command before completion of home return)” will generate.
