(8) Home return command (HOME) PLC output signal
Home return complete (HEND) PLC input signal
Home return operation starts at the leading edge of the HOME signal from “0” (OFF) to “1” (ON).
When the home return is complete, the HEND (home return complete) signal turns “1” (ON).
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) unless the power is turned off or the HOME signal is input
again. Accordingly, even after the initial home return is completed you can still perform home return
as many times as desired using the HOME signal.
Caution
1. In the case of a positioner operation axis operating in the position number specification mode or
command specification mode, issuing a positioning command to a given position immediately after
the power was turned on, without performing the home return first, will cause the actuator to
automatically return to its home and then execute the positioning, provided that this is the first
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 issued before completion of home return)” will generate.
