3.7.4 Using Speed Coincidence Output Signal
This section describes how to wire and use contact output signal “speed coincidence out-
put (/V-CMP).” This signal is output to indicate that actual motor speed matches a refer-
ence speed. The host controller uses this signal as an interlock.

Speed Coincidence Output For Speed Control
Only
This output signal indicates that actual motor
speed matches the input speed reference during
speed control.
ON
status:
Circuit between 1CN-25 and 1CN-26 is
closed.
1CN-25 is at low level. Actual motor speed matches the speed
reference (speed difference is below the
preset value).
OFF
status:
Circuit between 1CN-25 and 1CN-26 is
open.
1CN-25 is at high level. Actual motor speed does not match the
speed reference (speed difference is
greater than the preset value).
Preset value: Cn-22 (speed coincidence signal output width)
Use the following parameter to output the /V-CMP signal.
