Speed Coincidence Output
The basic use and wiring procedures for the speed coincidence (/V-CMP) output sig-
nal (photocoupler output signal), used to indicate a match with the speed reference,
are described below. The host controller uses the signal as an interlock.
Photocoupler output levels
per output node:
• Maximum operating
voltage: 30V
• Maximum output cur-
rent: 50mA
Output ð /V-CMP CN1-25
This signal is output when the actual motor speed during speed control is the same as the
speed reference input.

OFF
The following parameter setting is used to change the CN1 connector terminal that
outputs the /V-CMP signal.
Parameter

Output Signal Selections 1
The parameter is default set so the /V-CMP signal is output between CN1-25 and 26.
