Yaskawa Error Code A910 Link

For complex issues or persistent alarms that cannot be cleared, it is recommended to contact a certified repair center like Precision Zone for a full diagnostic. Yaskawa Servo Drive Alarm Codes Guide | PDF - Scribd

The "link" in this error refers to the connection between the physical motor performance and the drive’s monitored overload characteristics. The most common causes are:

To isolate whether the error is in the or the motor (encoder) : Swap the SERVOPACK with a known working spare. yaskawa error code a910 link

: Inspect the machinery for jams, excessive friction, or unexpected weight. Ensure the motor capacity is correctly sized for the operation.

The machinery is asking the motor to do more work than its physical profile allows. This happens frequently after a product line changeover, recipe modification, or cycle time speed-up. For complex issues or persistent alarms that cannot

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

| | Diagnostic Action | Likely Resolution | | :--- | :--- | :--- | | Wiring / Connection Fault | Visually inspect and physically tug on all cables and connectors. Check for oxidation or damage. | Re-seat or replace connectors. Replace damaged cables. Re-wire according to the manual. | | Mechanical Binding | Manually rotate the load shaft to feel for resistance. Disconnect the motor and spin by hand. | Repair or replace bearings, couplings, gearboxes, or linear guides. | | Excessive System Load | Use the drive's monitoring parameters to view motor torque, speed, and current during operation. | Reduce load, adjust cycle times (e.g., lower acceleration), or upgrade to a higher-capacity motor/drive. | | Brake Circuit Failure | Verify the brake is receiving correct voltage and is fully disengaging when the "Servo On" command is active. | Correct the voltage supply or replace a faulty brake coil. | | Servo Drive or Motor Failure | Perform a component swap test with a known good axis. If a component is found to be faulty, do not attempt internal repair. | Replace the faulty drive or motor. | : Inspect the machinery for jams, excessive friction,

Loose connectors at the encoder end or the SERVOPACK end.

Connect your PC to the drive using the Yaskawa SigmaWin+ Software Tool. Check the value of parameter Pn52B (Overload Warning Level). Ensure it matches factory defaults or calculated machine parameters. Look at your real-time effective torque monitors to determine if the drive is operating above 100% capacity continuously. 4.

Preventative Maintenance and Best Practices

Unplug and re-plug the encoder connectors (CN2) on the SERVOPACK and at the motor end. Ensure they are locked and properly seated [Source: SES Automations ].
