5.9.7 Multiturn Limit Disagreement Alarm (A.CC0)

5-78

Set the value, the desired rotational amount -1, to Pn205.

Note: The standard specification of the direct drive motor include an absolute encoder that shows values for a single rota-

tion, so the multiturn data (rotational serial data) for the encoder is always 0. The absolute value of the load side can
be created with the motor shaft angle only even when constructing an absolute position detecting system because the

servomotor and the load can be directly connected.

5.9.7 Multiturn Limit Disagreement Alarm (A.CC0)

When the multiturn limit set value is changed with parameter Pn205, a multiturn limit disagreement alarm

(A.CC0) will be displayed because the value differs from that of the encoder.

If this alarm is displayed, perform the operation described below and change the multiturn limit value in the

encoder to the value set in Pn205.

Operation

1

Press the MODE/SET Key to select the utility function.

2

Press the UP or DOWN Key to select Fn013.

3

Press the DATA/SHIFT Key for approximately one second.
"PGSEt" appears.

4

Press the MODE/SET Key. The value of the multiturn limit
setting in the absolute encoder will be the same as the value
of Pn205.
When the setting is completed, "donE" flashes for approxi-
mately one second.

5

Then, "donE" changes to "PGSEt".

6

Press the DATA/SHIFT Key for approximately one second.
"Fn013" is displayed again.

7

To enable the change in the setting, turn the power OFF and ON again.
