(10) Home return (HOME, HEND)
Home return is executed at ON edge (at startup of signal) of HOME (Home return).
When home return is completed, the HEND (Home return) signal is turned ON.
Turn OFF the HOME signal when the HEND signal is turned ON. Home return by the HOME signal is
also effective after home return is completed.
CAUTION
1. The position No. designated mode executes positioning after only the first one home return after power
is turned on is performed when positioning to a position is commanded without performing home return
when power is turned on.
2. Note that there occurs an alarm of “Error code 83 ALARM HOME ABS (absolute position moving
command in home return non-completion status) in cases other than the position No. designated mode.
(11) Zone (ZONE1, ZONE2)
In the case of the position No. designated mode, zone signals at two points can be outputted during
movement in an arbitrary region set as a parameter.
ZONE 1 (Zone 1) signal is turned ON in a region set to the parameter No.1 (zone boundary 1 + side) and
No.2 (zone boundary 1 - side).
ZONE 2 (Zone 2) signal is turned ON in a region set to the parameter No.23 (zone boundary 2 + side)
and No.24 (zone boundary 2 - side).
CAUTION
1. This signal supports the position No. designated mode only.
2. Use this signal in a status that home return is completed (HEND signal is ON).
If the HEND (home return completed) signal is ON, this signal is also effective even in the servo off
status or emergency stop status.
