4.5.9 Speed coincidence output
The speed coincidence (/V-CMP) output signal is output when the actual servomotor speed during
speed control is the same as the speed reference input. The host controller uses the signal as an
interlock.

After restart
Set the number of pulses for PG output signals(PAO,/PAO,PBO,/PBO) externally from the servodrive.
Feedback pulses from the encoder per revolution are divided inside the servodrive by the number set
in Pn200 before being output. (Set according to the system specifications of the machine or host
controller.)
The setting range varies with the number of encoder pulses for the servomotor used.
■Output Example
Pn200=16(when 16 pulses are output per revolution)

The /V-CMP signal is output when the difference between the speed reference and actual servomotor
speed is the same as the Pn503 setting or less.
■Example
The /V-CMP signal turns ON at 1900 to 2100min
-1
if the Pn501 parameter is set to 100 and the
reference speed is 2000min

This pin outputs the /COIN signal in position control mode, and the /V-CMP signal in speed control
mode.
