5.24 Absolute Encoders
5.24.5 Multiturn Limit Disagreement Alarm (A.CC0)
Pn205
Note: This parameter is enabled when you use an absolute encoder.
The data will change as shown below when this parameter is set to anything other than the
default setting.
• If the Servomotor operates in the reverse direction when the multiturn data is 0, the multiturn
data will change to the value set in Pn205.
• If the Servomotor operates in the forward direction when the multiturn data is at the value set
in Pn205, the multiturn data will change to 0.
Set Pn205 to one less than the desired multiturn data.
If you change the multiturn limit in Pn205, an A.CC0 alarm (Multiturn Limit Disagreement) will be
displayed because the setting disagrees with the value in the encoder. Refer to the following
section for the procedure to change the multiturn limit settings in the encoder.

Multiturn data
Information
5.24.5 Multiturn Limit Disagreement Alarm (A.CC0)
If you change the multiturn limit in Pn205 (Multiturn Limit), an A.CC0 alarm (Multiturn Limit Dis-
agreement) will be displayed because the setting disagrees with the value in the encoder.
Display
A.CC0
If this alarm is displayed, use the following procedure to change the multiturn limit in the
encoder to the same value as the setting of Pn205.

The multiturn data will always be 0 in the following cases. It is not necessary to reset the
absolute encoder in these cases.
• When you use a single-turn absolute encoder
• When the encoder is set to be used as a single-turn absolute encoder (Pn002 = n.
Absolute encoder-related alarms (A.810 and A.820) will not occur.
