Sigma II User’s Manual Chapter 5: Parameter Settings and Functions5-755.5.4 Speed Coincidence Output (/V-CMP)The basic use and wiring procedures for the speed coincidence (/V-CMP) outputsignal (photocoupler output signal), used to indicate a match with the speedreference, 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 asthe speed reference input.The following parameter setting is used to change the CN1 connector terminal thatoutputs 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.Output /V-CMP CN1-25 Speed Coincidence OutputSignal Speed Control/V-CMPState Status ResultON Circuit between CN1-25 and 26 isclosed, and CN1-25 is at low level. Speed coincides. (Speed error is belowthe setting).OFF Circuit between CN1-25 and 26 isopen, and CN1-25 is at high level. Speed does not coincide.
