5.3.6 Using the /INPOSITION Output Signal
The basic use and wiring procedure for the positioning completed (/INPOSITION)
output signal (photocoupler output signal) is described below. The signal is output to
indicate that servomotor operation is completed.
This signal indicates that servomotor movement has been completed. The /INPOSI-
TION output signal turns ON when the position error is within the inposition win-
dow width, Pn821, and when the position distribution ends (DEN). The Indexer
continuously outputs position commands while positioning, similar to a pulse train.
This is known as a “distribution”. Therefore, the /INPOSITION output signal does
not turn on while the distribution continues.
The following parameter is used to set the number of error pulses.
Set the number of error pulses in reference units.
The /INPOSITION width setting has no effect on final positioning accuracy.

State
Status Result (default state)
ON
Circuit between CN4–19 and 20 is
closed. Positioning is completed. (Position error is
below the setting.)
OFF
Circuit between CN4–19 and 20 is
open. Positioning is not completed. (Position
error is above the setting.)
