8.6 Operating Using Position Control8.6.6 Positioning Near SignalThis signal indicates that the positioning of the servomotor is near to completion, and is generally used in combinationwith the positioning completed (/COIN) output signal.The host controller receives the positioning near signal prior to confirming the positioning-completed signal, andperforms the following operating sequence after positioning has been completed to shorten the time required foroperation.TypeSignalNameConnectorPin NumberSettingMeaningOutput /NEAR Must be allocated ON (low level) The servomotor has reached a point near to positioningcompleted.OFF (high level) The servomotor has not reached a point near to positioningcompleted.The output terminal must be allocated with parameter Pn510 in order to use positioning near signal. Refer to 7.3.3 OutputCircuit Signal Allocation for details.Pn504NEAR Signal WidthPositionSetting Range Setting Unit Factory Setting Setting Validation1 to 250 Reference units 7 ImmediatelyThe positioning near (/NEAR) signal is output when the difference(error) between the number of reference pulses output byReferenceMotor speedthe host controller and the travel distance of the servomotor isSpeedless than the value set in Pn504.Set the number of error pulses in reference units (the number ofPn504 Pn500input pulses defined using the electronic gear.)Error pulseNormally, the setting should be larger than that for the positioning0completed width(Pn500)./NEAR/COIN88-59
