Output → COIN 1CN-8
For position control (SGDA-jjjP) only.
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.
Circuit between 1CN-8 and 1CN-10 is
ON
closed.
status:
1CN-8 is at low level.
Circuit between 1CN-8 and 1CN-10 is
OFF
open.
status:
1CN-8 is at high level.
Preset Value: Cn-1B (positioning complete range)
2) Set the number of error pulses in the following user constant to adjust output timing of
COIN (positioning complete output).
COINLV
Cn-1B
For position control (SGDA-jjjP) only.
This user constant is used to set output timing of
positioning complete signal (COIN, 1CN-8) to be
output when motor operation is complete after a
position reference pulse has been input.
Set the number of error pulses in terms of reference unit (the number of input pulses that
is defined using the electronic gear function).
If too large a value is set in this user constant, error may become too small when the mo-
tor runs at a low speed, causing COIN to be output continuously.
COINLV does not affect the final positioning accuracy.

Positioning Complete Output

Positioning is complete (position error is
below the preset value).
Positioning is not complete (position
error is over the preset value).
