YASKAWA Sigma-7 SGD7S Series

The data will change as shown below when this parameter is set to anything other than
the default setting.
n 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.
n 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.
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.

The multiturn data will always be 0 in the following cases. It is not neces-
sary to reset the absolute encoder in these cases.

When the encoder is set to be used as a single-turn absolute encoder

Absolute encoder-related alarms (A.810 and A.820) will not occur.
7.9.9 Multiturn Limit Disagreement Alarm (A.CC0)
If you change the multiturn limit in Pn205 (Multiturn Limit), an A.CC0 alarm (Multiturn
Limit Disagreement) will be displayed because the setting disagrees with the value in the
encoder.
Display Name Meaning
A.CC0 Multiturn Limit Disagree-
ment
Different multiturn limits are
set in the encoder and
SERVOPACK.
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 following table lists the tools that you can use to set the multiturn limit.Applicable Tools
