Speed Coincidence Output For Speed/Torque
Control Only
For speed/torque 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)

signal V-CMP

Set the output conditions for speed coincidence
signal V-CMP
+ (1CN-25).
V-CMP
+ signal is output when the difference be-
tween the reference speed and actual motor
speed is not greater than the preset value.
Example: When preset value is 100 and reference speed is 2000 r/min.
V-CMP
+ is ON (circuit between 1CN-25 and 1CN-26 is closed) when the speed is be-
tween 1900 and 2100 r/min.
