Set the value, the desired rotational amount -1, to Pn205.
5.9.7 Multiturn Limit Disagreement Alarm (A.CC0)
When the multiturn limit set value is changed with parameter Pn205, a multiturn limit disagreement alarm
(A.CC0) will be displayed because the value differs from that of the encoder.
If this alarm is displayed, perform the procedure given in (2) Operating Procedure to change the multiturn
limit value in the encoder to the value set in Pn205.
(1) Preparation
The following condition must be met to clear the alarm and change the multiturn limit value.
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
(2) Operating Procedure
Use the following procedure.
Factory Setting (= 65535) Other Setting ( ≠ 65535)

Step Display after Operation Keys Operation
1
Press the Key to select the utility function mode.
And press the or Key to select the Fn013.
2
Press the Key to view the execution display of
Fn013.
Note: If the display is not switched and “NO-OP” is
displayed in the status display, the Write Pro-
hibited Setting (Fn010 = 0001) is set. Check
the setting and reset.
3
Press the Key to set the multiturn limit value.
When the setting is completed, the status display
shows "DONE" for one second. The status display
then returns to show "A.CC0" again.
Note: If the
Key is pressed instead of the
Key, the multiturn limit value will not be reset.
