Yaskawa Error Code A910 Link [ TRUSTED 2026 ]

The Yaskawa error code Overload Warning . It serves as a precursor to more severe overload alarms like A.710 (High Load) or A.720 (Low Load). If this warning is ignored, the drive will eventually trigger a hard fault and stop the motor. Common Causes Mechanical Stress

: The motor capacity is too small for the actual application requirements. Faulty Wiring/Encoder

By methodically following the steps above—checking sub-errors, cleaning contacts, reseating cards, and verifying parameters like H5-01 —you can restore the "link" and return your automation system to full operation. Remember: A910 is an alarm, not a death sentence. Treat it as a maintenance prompt, and your Yaskawa drive will continue to perform for years. yaskawa error code a910 link

| 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. |

Yaskawa servo systems, particularly the Sigma-7 and Sigma-5 series, are renowned for their reliability and precision. However, when a appears on your SERVOPACK display, it signals a critical communication breakdown between the drive and its peripheral components or the motion controller.

Verify that connections between the Servopack's U, V, W terminals and the motor are secure and not creating a ground fault or short-circuit . Step 3: Verify and Adjust Parameters The Yaskawa error code Overload Warning

If your machine displays A.910, follow these steps to resolve the issue: 1. Check Wiring Connections (Encoder and Motor)

In some cases, the encoder type settings within the drive parameters (

The most common cause of an overload warning is a physical restriction in the automated machinery. Common Causes Mechanical Stress This public link is

Check the motor's actual operating characteristics using SigmaWin+ Engineering Software . Optimize the motion profile by reducing peak acceleration times, decreasing the maximum speed reference, or extending dwell times between movements. If the application demands the current throughput, upgrade to a larger capacity motor and SERVOPACK. 3. Faulty or High-Resistance Wiring

Consider increasing the motor capacity if the load requirement is legitimate. Remedy Summary for A910 Action to Take Wiring Ensure Servomotor/Encoder are correctly wired. Load

In Sigma 7 SERVOPACKs, the warning sensitivity is governed by the parameter . If this parameter is set too low (e.g., below the factory default of 20%), the drive will throw an A.910 code during entirely normal, safe operating profiles. 5. High Cabinet Temperatures or Hardware Failure
