The following table shows the proper operating mode settings for different
drivers and applications.
Driver
Stepping motor driver (See note.)
Servo driver
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 N.O. 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.

executed.
Remarks
Use this mode when you want to
reduce the processing time, even at
the expense of positioning accuracy.
(The Servo Driver's positioning com-
plete signal is not used.)
Use this mode when you want high
positioning accuracy. (The Servo
Driver's positioning complete signal is
used.)
Origin Input Signal goes from OFF
to ON while motor is decelerating.
