4 Operation
4.7.7 Multiturn Limit Disagreement Alarm (A.CC0)
4-48
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.
4.7.7 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.
This setting can be performed with the adjustment command (ADJ).
For information the adjustment command (ADJ), refer to Σ -V Series User’s Manual MECHATROLINK-II
Commands (No.: SIEP S800000 54).

Step Display after Operation Keys Operation
1
Press the Key to select the utility function. And
press the or Key to select the Fn013.
2
Press the Key to view the execution display of
Fn013.
Note: If the display is not switched and “NO-OP” is
displayed in the status display, the Write Pro-
hibited Setting (Fn010 = 0001) is set. Check
the setting and reset.
3
Press the Key to set the multiturn limit value.
When the setting is completed, the status display
shows "DONE" for one second. The status display
then returns to show "A.CC0" again.
Note: If the
Key is pressed instead of the
Key, the multiturn limit value will not be reset.
