Yaskawa Error Code A910 |link| Info

Ensure U, V, and W power phases and encoder cables are secure.

In this specific case, the warning appears at power-on, but the motor operates normally. The fix is to properly reset the alarm history.

If the error persists after testing cables and connections, the encoder within the motor may be faulty, requiring motor replacement or repair. Alternatively, the SERVOPACK itself may have a damaged internal circuit for CN2 .

: Ensure the motor and encoder cables are securely connected and free of damage. High-resistance connections can lead to increased current draw. yaskawa error code a910

“Always is,” Jenna replied, finishing her cold coffee. “The drive just has good manners. It tells you it’s sick before it tries to run a marathon.”

If you operate or maintain automated machinery, encountering an interruption can stall production and impact your bottom line. Among industrial motion control systems, Yaskawa AC servo drives—specifically the Sigma-5, Sigma-7, and Sigma-10 series—are industry standards for precision and reliability. However, like any sophisticated electronics, they display specific codes when something goes wrong. Ensure U, V, and W power phases and

Solution C: Reset the Fan Lifetime Parameter (Mandatory After Replacement)

If the load is consistently too heavy, a higher-capacity motor/drive combo may be required. If you are currently facing this error, let me know:

Poor contact or incorrect wiring between the servomotor and the encoder can trigger false or early warnings. If the error persists after testing cables and

In the Yaskawa ecosystem, it is critical to distinguish between an and a Fault (Trip) .

Disclaimer: This information is for educational purposes. Always refer to the specific Yaskawa user manual for your drive model for the most accurate troubleshooting steps, as codes can vary slightly between Sigma-II, Sigma-V, and Sigma-7 models.

: If the mechanics are fine but the alarm persists during normal operation, the motor capacity may be insufficient for the application. Important Note: A.910 vs. A.810
