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).
