7.1 I/O Signal Allocations7.1.9 /NEAR (Near) Signal7-117 Application FunctionsSetting the Output Timing of the /COIN (Positioning Com-pletion Output) SignalYou can add a reference input condition to the output conditions for the /COIN signal tochange the signal output timing.If the position deviation is always low and a narrow positioning completed width is used,change the setting of Pn207 = n.X (/COIN (Positioning Completion Output) Signal OutputTiming) to change output timing for the /COIN signal.7.1.9 /NEAR (Near) SignalThe /NEAR (Near) signal indicates when positioning completion is being approached.The host controller receives the NEAR signal before it receives the /COIN (Positioning Comple-tion) signal, it can start preparations for the operating sequence to use after positioning hasbeen completed. This allows you to reduce the time required for operation when positioning iscompleted.The NEAR signal is generally used in combination with the /COIN signal.Note: You must allocate the /NEAR signal to use it. Use Pn510 = n.X (/NEAR (Near) Signal Allocation) to allo-cate the signal to a connector pin. Refer to the following section for details.7.1.2 Output Signal Allocations on page 7-5Parameter Description WhenEnabled ClassificationPn207(2207h)n.0(default setting)Output the /COIN signal when the absolute value ofthe position deviation is the same or less than thesetting of Pn522 (Positioning Completed Width).Afterrestart Setupn. 1Output the /COIN signal when the absolute value ofthe position deviation is the same or less than thesetting of Pn522 (Positioning Completed Width) andthe reference after the position reference filter is 0.n. 2Output the /COIN signal when the absolute value ofthe position deviation is the same or less than thesetting of Pn522 (Positioning Completed Width) andthe reference input is 0.Type Signal Connector Pin No. 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.
