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.
Explanation of the Origin Search Parameters
Operating Mode
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.
The following table shows the proper operating mode settings for different
drivers and applications.
Note
There are stepping motor drivers that are equipped with a positioning com-
pleted signal like a Servo driver. Operating modes 1 and 2 can be used with
these stepping motor drivers.

Remarks: Operations Detecting the Origin During Deceleration from High
Speed
Operating Mode 0 (without Error Counter Reset Output, without
Positioning Completed Input)
Connect the sensor's open collector output signal to the Origin Input Signal.
The Origin Input Signal's response time is 0.1 ms when set as a NO contact.
When the Origin Proximity Input Signal is received, the motor will begin decel-
erating from the origin search high speed to the origin search proximity speed.
In this operating mode, the Origin Input Signal will be detected if it is received
during this deceleration and an Origin Input Signal Error (error code 0202) will
be generated. In this case, the motor will decelerate to a stop.

Not used.
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.

Goes ON for 20 to
30 ms when the
origin is detected.
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.
2
After the origin is
detected, the origin
search will not be end
until the Positioning
Completed Input is
received from the driver.

Use this mode when you want to
reduce the processing time, even at the
expense of positioning accuracy. (The
Servo Driver's positioning complete
signal is not used.)

Use this mode when you want high
positioning accuracy. (The Servo
Driver's positioning complete signal is
used.)
