8.7.6 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 operation described below and change the multiturn limit value in the
encoder to the value set in Pn205.
Use SigmaWin for Σ-V-SD (MT) to change the multiturn limit.
Setup (Initialization) can be performed using EtherCAT (CoE) command (Object 2310h:1).
For EtherCAT (CoE) command, refer to
Σ
-V-SD series User’s Manual For Command Profile EtherCAT (CoE)
Communications Reference (manual no.: SIEP S800000 95).
Follow the steps below to set the multiturn limit to the Σ-V-SD driver and the servomotor.
1. In the SigmaWin for Σ-V-SD (MT) component main window, click Setup, print to Set Absolute
Encoder and click Multi-Turn Limit Setting. A verification message appears confirming if you
want to continue although the position data will change.
Click Cancel to return to the main window without setting the multiturn limit.
2. Click Continue, and the Multi-Turn Limit Setting box appears.
