•
If the motor operates in the reverse direction when the multiturn data is 0, the multiturn data
will change to the value set in Pn205.
•
If the motor 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.
6.12.9
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 and the applicable
tool functions.
