For Position
Control
This parameter is used to set output timing of position-
ing complete signal (/COIN) to be output when motor
operation is complete after a position reference pulse
has been input.
Set the number of error pulses in terms of reference
unit (the number of input pulses that is defined using
the electronic gear function).
If too large a value is set in this parameter, error may become too small when the motor runs at
a low speed, causing /COIN to be output continuously.
COINLV does not affect the final positioning accuracy.
2.7.4 Speed Coincidence Output
This section describes how to wire and use contact output signal “speed coincidence output
(/V-CMP).” This signal is output to indicate that actual motor speed matches a reference
speed. The host controller uses this signal as an interlock.

Control
This output signal indicates that actual motor speed
matches the input speed reference during speed con-
trol.
ON
status:
Circuit between CN1-8 and CN1-3 is
closed.
CN1-8 is at low level. Actual motor speed matches the speed
reference (speed difference is below the
preset value).
OFF
status:
Circuit between CN1-8 and CN1-3 is
open.
CN1-8 is at high level. Actual motor speed does not match the
speed reference (speed difference is
greater than the preset value).
