Origin Search Operation Section 8-2
Axis Parameter Area The following parameters are for the operation mode for origin searches.
d = 1860 hex + (Axis No.
−
1)
×
14 hex
Note (1) The reversal mode 3 setting for the origin search operation, the origin de-
tection method, and the origin search preset can be used only with Posi-
tion Control Units with unit version 2.0 or later. They cannot be used with
Position Control Units with unit version 1.3 or earlier.
(2) Make sure that the same direction is set for the origin search direction in
the Axis Parameters and Zero Point Return Direction for W-series Servo
Drives (Pn816) or Origin Return Mode Settings for G-series Servo Drives
(Pn108) in the Servo Parameters. Setting different directions may result
in a malfunction.
(3) When using an absolute encoder, make sure that the settings for the en-
coder type in the Axis Parameters and Operation Switch when Using Ab-
solute Encoder (Pn002.2 for W Series and Pn00B for G Series) in the
Servo Parameters match. If the settings do not match, ORIGIN SEARCH
execution will not be possible, or another malfunction may occur.
(4) Make sure that the external input signals for origin searches (limit input
signal and origin proximity input signal) maintain a signal width no shorter
than the MECHATROLINK communications cycle. If the input signal width
