For Speed
Control Only
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 min
−1
.
/V-CMP is ON (circuit between 1CN-25 and 1CN-26 is closed) when the speed
is between 1900 and 2100 min
−1
.
NOTE
/V-CMP is a signal for speed control.
For position control, /COIN (position complete output) is used instead. For torque control,
/V-CMP is always ON.
