Yaskawa Error Code A910 Exclusive 📌

Log and monitor

The A910 exclusive error code is a specific error message that appears on Yaskawa servo drives or robots when a problem occurs. This error code indicates that there is an issue with the axis's position or movement. When the drive or robot detects an error, it will display the A910 exclusive error code, and the machine will typically shut down to prevent further damage.

Over time, mechanical components degrade. Dry linear rails, failing ball screws, worn-out gearboxes, or physical debris blocking the axis travel create immense mechanical resistance. The servo motor must exert significantly higher torque than normal to reach its commanded position, driving up the electrical current. 2. Misconfigured Overload Warning Level (Parameter Pn52B)

, encountering error codes is an inevitable part of equipment lifecycles.

Do not swap the drive. Swap the digital operator with a brand new or known working unit from another machine of the exact same model .

: This triggers when the system reaches a specific percentage (typically 20% to 100% based on user configuration) of the ultimate shutdown limit. The drive continues to run, but the digital operator flashes the code, and a assigned digital output trips. Log and monitor The A910 exclusive error code

: Potential faulty contact in the motor or encoder wiring, or a rare failure within the Yaskawa SERVOPACK itself. How to Resolve It

Technical Comparison Matrix: A.910 Behavior Across Generations Yaskawa Drive Generation Specific Code Meaning Common Underlying Culprit Primary Parameter Control Pre-Overload Warning Internal control cabinet temperatures exceeding 55°C. Pn52B (Overload Warning Level) Sigma 5 (SGDV) Pre-Overload Warning Mechanical binding or incorrect linear scale configuration. Pn52B (Overload Warning Level) Sigma 7 (SGD7S) Pre-Overload Warning

: Check the motor power cable and the encoder cable for breaks, sharp bends, or shielding degradation. Tighten all terminal screws at the SERVOPACK and clean any carbon tracking or corrosion on the motor plugs. 4. Aggressive Motion Profiles or Motor Under-Sizing Over time, mechanical components degrade

Sometimes the issue is not with the servo system at all but with the machinery it drives. Mechanical binding, seized bearings, misaligned couplings, or jammed workpieces can all impose excessive torque demands on the motor.

: If you change Pn52B to a higher value to eliminate nuisance A.910 warnings, you are reducing the safety margin for your motor. Increasing Pn52B too much may prevent the A.910 warning from appearing at all, potentially leading to an unexpected A.710 alarm and machine downtime. Adjust this parameter conservatively and with a full understanding of your load cycle.
