Note An origin search will not be started unless the origin search proximity speed is
less than the origin search high speed and unless the origin search/return ini-
tial speed is less than the origin search proximity speed.
The operating mode parameter specifies the kind of I/O signals that are used
in the origin search. The 3 operating modes indicate whether the Error
Counter Reset Output and Positioning Completed Input are used.

Remarks
Operation when the origin is
detected during deceleration from
the origin search's high speed
The Origin Input Signal will be
detected during deceleration. An Ori-
gin Input Signal Error (error code
0202) will occur and the motor will
decelerate to a stop.
The Origin Input Signal will not be
detected during deceleration. When
the Origin Input Signal is detected
after the motor has reached the prox-
imity speed for origin search, the
motor will be stopped and the origin
search operation will end.
