Yaskawa Σ-V Series AC Servo Drives Rotational Motor MECHATROLINK-III - Manual (Page 101)

4 Operation
4.7.6 Multiturn Limit Disagreement Alarm (A.CC0)
4-36
Set the value, the desired rotational amount -1, to Pn205.
4.7.6 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 procedure given in (2) Operating Procedure to change the multiturn
limit value in the encoder to the value set in Pn205.
(1) Preparation
The following condition must be met to clear the alarm and change the multiturn limit value.
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
(2) Operating Procedure
Use the following procedure.
This setting can be performed with the write memory command (MEM_WR).
For information the write memory command (MEM_WR), refer to Σ -V Series User’s Manual MECHA-
TROLINK-III Standard Servo Profile Commands (Manual No.: SIEP S800000 63).

Setting .
A verification message will appear confirming if you want to continue although the position data will
change.
Click Cancel to return to the main window without setting the multi-turn limit.
