Ensure the machine is not carrying more than the maximum permitted load.
On legacy architectures like the Sigma-II Series , warning codes are only transmitted to host controllers if this parameter is correctly mapped ( Pn001 = n.1 Berlin/Standard Configuration ). 5 Root Causes and Targeted Remedies
Route encoder cables away from high-voltage cables and VFDs to minimize electromagnetic interference (EMI). 3. Replace the Encoder Cable yaskawa error code a910 link
Follow this systematic, step-by-step procedure to identify and eliminate the root cause. Start with the safest, most common causes and work your way toward more involved possibilities.

| Feature | A.910 Overload Warning | True "Link" Communication Error (e.g., bUS, CE) | | :--- | :--- | :--- | | | Mechanical or electrical overload. Network is fine. | Failure in serial or fieldbus network (e.g., EtherNet/IP, Profibus). | | "Link" LED State | Typically active/normal. The link to the controller is still established. | Often OFF or Flashing , indicating a physical break in the network cable. | | Common Error Codes | A.910 , A.710 , A.720 | bUS (Option comms error), CE (Modbus error), EF0 (External fault). | | Primary Causes | Jammed motor, loose power cables, high load, mechanical binding. | Disconnected network cable, damaged connector, incorrect IP/node address. |

Comprehensive Guide to Troubleshooting Yaskawa Error Code A910: Link Fault and Overload Warnings
The primary function of the A.910 warning is to monitor the continuous root-mean-square (RMS) load of the motor. When the drive detects that the torque requirements have exceeded the continuous rating of the specific motor-drive combination for a sustained period, it throws the A.910 code.
