5.5.3 Using the Positioning Completed Output Signal (/COIN)
The basic use and wiring procedure for the positioning completed (/COIN) 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 during position
control. The host controller uses the signal as an interlock to confirm that
positioning is completed.

0
Enables the servo ON
(/S-ON) input signal.
The servo is OFF when CN-40 is open, and is ON when
CN1-40 is at 0V.
7
Disables the servo ON
(/S-ON) input signal.
The servo is always ON, and has the same effect as
shorting CN1-40 to 0V.
