Origin Search Operation
Section 8-2
Note
To use a motor with absolute encoders with the OMNUC G series and G5
series Servo Drives, use the motor as described below when setting the abso-
lute PG origin offset using origin search.
• If the limit input in the origin search direction is ON when executing the
origin search, origin search does not operate normally.
Start the origin search after moving the position where the limit input in
the origin search direction does not turn ON by jogging.
• If the origin search is started when the limit input is ON in the origin
search direction, an error terminates when the origin search operation is
completed (data setting error, error code: 3099).
