5.5.4 Speed Coincidence Output (/V-CMP)
The basic use and wiring procedures for the speed coincidence (/V-CMP) output
signal (photocoupler output signal), used to indicate a match with the speed
reference, are described below. The host controller uses the signal as an interlock.
This signal is output when the actual motor speed during speed control is the same as
the speed reference input.
The following parameter setting is used to change the CN1 connector terminal that
outputs the /V-CMP signal.
The parameter is default set so the /V-CMP signal is output between CN1-25 and 26.
See 5.3.4 Output Circuit Signal Allocation for more details on parameter Pn50E.

ON
Circuit between CN1-25 and 26 is
closed, and CN1-25 is at low level.
Speed coincides. (Speed error is below
the setting).
OFF
Circuit between CN1-25 and 26 is
open, and CN1-25 is at high level.
Speed does not coincide. (Speed error
is above the setting).
