After restart
Set the number of pulses for PG output signals(PAO,/PAO,PBO,/PBO) externally from the servo drive.
Feedback pulses from the encoder per revolution are divided inside the servo drive 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)
PAO
PBO
1 revolution
Preset value：16
4.5.6 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.

Immediately
The /V-CMP signal is output when the difference between the speed reference and actual servomotor speed is less than
Pn501.
■Example
The /V-CMP signal turns ON at 1900 to 2100rpm ifthe Pn501 parameter is set to 100 and the reference speed is 2000rpm.

/V-CMP is output in this range.

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