5.3 Sequence I/O Signals5.3.2 Output Signals5-16The NEAR signal is generally used in combination with the /INPOSITION (Positioning Comple-tion Output) signal.Note: You must allocate the /NEAR signal to use it. Use PnBCE = n.X (/NEAR (Near Output) Signal Allocation)to allocate the signal to a connector pin. Refer to the following section for details.5.3.4 Allocating Output Signals to Pins and Parameter Settings on page 5-20 Setting the Position Near WidthYou set the condition for outputting the /NEAR (Near Output) signal in PnB2F (Near Width). The/NEAR signal is output when the difference between the target position and current position isequal to or less than the setting of PnB2F.Note: Normally, set PnB2F to a value that is larger than the setting of PnB2D (Positioning Completed Width)./V-CMP (Speed Coincidence Detection Output) SignalThis signal is output when the Servomotor speed is the same as the reference speed.Note: You must allocate the /V-CMP signal to use it. Use PnBCF = n.X (/V-CMP (Speed Coincidence Detec-tion Output) Signal Allocation) to allocate the signal to a connector pin. Refer to the following section fordetails.5.3.4 Allocating Output Signals to Pins and Parameter Settings on page 5-20/POSRDY (Homing Completed Output) SignalThis signal is output when the position information becomes valid after homing is completed.Note: Use PnBD2 = n.X (/POSRDY (Homing Completed Output) Signal Allocation) to allocate the /POSRDYsignal to another connector pin. Refer to the following section for details.5.3.4 Allocating Output Signals to Pins and Parameter Settings on page 5-20Type Signal Pin Signal Status MeaningOutput /NEAR Must be allocated.ON (closed) The Servomotor has reached a pointnear to positioning completion.OFF (open) The Servomotor has not reached apoint near to positioning completion.PnB2FNear WidthSetting Range Setting Unit Default Setting When Enabled Classification1 to 99,999 Reference units 10 Immediately SetupType Signal Pin Signal Status MeaningOutput /V-CMP Must be allocated.ON (closed) The Servomotor speed is the same as the ref-erence speed.OFF (open) The Servomotor speed is not the same as thereference speed.Type Signal Pin Signal Status MeaningOutput /POSRDY 28 [default setting] ON (closed) The position information is valid.OFF (open) The position information is not yet valid.SpeedPosition deviationReference Speed Motor speed/NEAR signal/INPOSITION signalPnB2DPnB2F
