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.
Applicable Tools
The following table lists the tools that you can use to set the multiturn limit and the applicable

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.2)
Absolute encoder-related alarms (A.810 and A.820) will not occur.
