3.7.3 Using Positioning Complete Signal
1) This section describes how to wire and use contact output-signal “positioning complete
output (COIN
).” This signal is output to indicate that servomotor operation is complete.

This output signal indicates that motor operation
is complete during position control. The host con-
troller uses this signal as an interlock to confirm
that positioning is complete.
ON
status:
Circuit between 1CN-25 and 1CN-26 is
closed.
1CN-25 is at low level.
Positioning is complete (position error is
below the preset value).
OFF
status:
Circuit between 1CN-25 and 1CN-26 is
open.
1CN-25 is at high level.
Positioning is not complete (position
error is over the preset value.)
Preset Value: Cn-1B (positioning complete range)
2) Set the number of error pulses in the following user constant Cn-1B to adjust output tim-
ing of COIN (positioning complete output).
