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.
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.
Default Setting
Not Default Setting
When the encoder is set to be used as a single-turn absolute encoder (Pn002 = n.
2
),
the multiturn data will always be zero. It is not necessary to reset the absolute encoder. Also,
an alarm related to the absolute encoder (A.810 or A.820) will not occur.
