4.5 Absolute Encoders
4-43
Operation
Set the value, the desired rotational amount -1, to Pn205.
Note:
A direct-drive servomotor with the standard specifications has a single-turn absolute encoder mounted. It is possible to
directly connect the servomotor and the load, and so absolute values can be created at the load by using only the angle of
the motor shaft even when constructing an absolute value detection system. Therefore, encoder multiturn data is not
required.
4.5.7 Multi-turn Limit Disagreement (A.CC0)
When the multiturn limit set value is changed with parameter Pn205, an alarm A.CC0 (multi-turn limit dis-
agreement) 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 multi-turn limit value in the
encoder to the value set in Pn205

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.

Press the Key to return to the display the proce-
dure 1.
5 To enable the change in the setting, turn the power OFF and ON again.
