Yaskawa Error Code A910 Link -

The Yaskawa error code A910 link is fundamentally a communication handshake problem between the drive’s brain and its add-on card. It is rarely a catastrophic failure; more often, it is a loose screw, a dirty contact, or a parameter mismatch.

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.


FAQ: Quick Answers on A910


By mastering the "link" in Yaskawa error code A910, you turn a frustrating downtime event into a 15-minute scheduled repair. Keep this guide near your panel, and always keep spare option card contact cleaner in your tool kit.

Yaskawa error code A.910 Overload Warning that appears on Sigma series servo drives

(such as Sigma-7, Sigma-5, and Sigma-3). It is not a terminal fault but a proactive alert indicating that the motor is operating near its thermal limit and is at risk of triggering a full overload alarm (A.710 or A.720). Understanding the A.910 Warning

Unlike a hard fault that stops the motor immediately, A.910 acts as a precursor. If the underlying cause is not addressed, the drive will eventually trigger a protective shutdown to prevent hardware damage. Description Warning (Pre-alarm) Primary Meaning Overload (Approaching thermal limit) Associated Alarms A.710 (Instantaneous Overload), A.720 (Continuous Overload) Common Causes yaskawa error code a910 link

The A.910 warning typically stems from mechanical stress or electrical configuration issues: Mechanical Overload

: Excessive load on the motor due to mechanical friction, jamming, or binding in the machinery. Incorrect Wiring

: Faulty contacts or incorrect wiring in the servomotor or encoder cables. Operational Demands

: The application is exceeding the rated torque or speed characteristics of the motor. Parameter Settings : The overload warning level ( cap P n 52 cap B ) is set too low for the specific application. High Ambient Temperature : If the temperature inside the SERVOPACK panel exceeds 55 raised to the composed with power cap C , it can trigger thermal warnings. Troubleshooting and Solutions To resolve the A.910 error, follow these diagnostic steps: Inspect Mechanical Components

Check for physical obstructions or increased friction in the drive train.

Verify that the motor capacity is correctly matched to the load requirements. Verify Wiring Integrity The Yaskawa error code A910 link is fundamentally

Ensure all motor and encoder cables are securely connected and free from damage.

Confirm that grounding is properly installed to prevent electrical noise interference. Adjust Parameters Review parameter

(Overload Warning Level). Adjusting this value can provide more headroom if the application naturally runs close to the limit without actually risking damage. Check Environmental Conditions

Ensure the cooling fans in the control panel are functional and that the ambient temperature remains within the specified range (typically below 55 raised to the composed with power cap C Evaluate Hardware

If the warning persists despite mechanical and wiring checks, the SERVOPACK internal circuitry may be faulty and might require replacement. using the SigmaWin+ software? Yaskawa Servo Drive Alarm Codes Guide | PDF - Scribd

Here’s a quick guide to the Yaskawa error code A910 (often seen on Yaskawa V1000, J1000, GA700, GA800, and other A1000-series drives): FAQ: Quick Answers on A910


If you have a second identical drive or known-working option card:

  • Check motor cable

  • Check motor windings

  • Check for external contactor

  • Temporarily disable detection (for test only)

  • Test drive with a known good motor


  • If using V/f Control (no auto-tuning):


    Do not simply cycle power. Follow this structured approach.
