Position Control
Thisuser constantisusedto setoutput timingfor thepositioning completedsignal (/COIN)when
the position reference pulse is input and Servomotor operation is completed.
Set the number of error pulses in reference units (the number of input pulses defined using the
electronic gear function).
Too large a value set at this user constant may output only a small error during low-speed opera-
tion that will cause the /COIN signal to be output continuously.
The positioning completed width setting has no effect on final positioning accuracy.
/COIN is a position control signal.
With the factory setting, this signal is used for the speed coincidence output /V-CMP for speed control, and it
is always ON for torque control.
5.5.4 Speed Coincidence Output
The basic use and wiring procedures for the speed coincidence (/V-CMP) output signal used to
indicate a match with the speed reference (photocoupler output signal) are described below. The
host controller uses the signal as an interlock.

Speed Coincidence Output
Speed Control
This signal is output when the actual motor speed during speed control is the same as the speed
reference input.
ON:
Circuit between CN1-25 and 26 is closed,
and CN1-25 is at low level.
Speed coincides. (Speed error is below the
setting.)
OFF:
Circuit between CN1-25 and 26 is open, and
CN1-25 is at high level.
Speed does not coincide. (Speed error is
above the setting.)
