Origin Search Operation
Section 8-2
Note
(1) The reversal operation for an origin search in the reverse direction is ex-
ecuted either when the origin proximity input signal turns OFF during the
origin search in the reverse direction, or when the limit input signal turns
ON during the origin search in the reverse direction while the origin prox-
imity input signal is ON, whichever occurs first.
(2) The signal width of the origin input signal must be longer than the
MECHATROLINK communications cycle when the Origin Proximity Input
Signal parameter is set to 2 (Not use origin proximity input signal) during
Origin search operation
mode
3: Reversal mode 2
(unit version 2.0 or later)
Origin detection method
0: With origin proximity input
signal reversal
1: Without origin proximity
input signal reversal (unit ver-
sion 2.0 or later)
2: Not use origin proximity
input signal (unit version 2.0
or later)
Cannot be set. (An axis parameter check error (error code: 3091) will occur when the data
is transferred.)
