Yaskawa Error: Code A910

The on a Yaskawa SERVOPACK typically signifies a specific type of encoder communication error or encoder mismatch error , often related to a "serial encoder data mismatch" or "encoder communication error" depending on the specific model of the drive.

The most frequent cause is an issue with the load itself. Something is making the motor work harder than it should.

Faults within the power transmission path can mimic a high-load scenario.

Keep track of the age of mechanical couplers and gearboxes. As gearboxes wear out internally, their efficiency drops, shifting the mechanical burden directly onto the Yaskawa motor. The on a Yaskawa SERVOPACK typically signifies a

: High temperatures inside the SERVOPACK panel (exceeding ) can reduce performance and trigger warnings. Troubleshooting & Solutions To resolve an A.910 warning, follow these diagnostic steps:

If you ignore the A910 warning and keep running the drive, the heat inside the chassis will rapidly build up. Once the heatsink reaches its maximum thermal threshold, the drive will trip on an oH1 (Overheat 1) fault. When a fault occurs, the drive immediately cuts power to the motor to prevent the Insulated Gate Bipolar Transistors (IGBTs) from melting. : High temperatures inside the SERVOPACK panel (exceeding

The most common cause of an overload warning is an unexpected physical resistance in the driven machinery. Over time, components wear down, causing the motor to pull more current to achieve the same movement.

A910 is not a universal code for all Yaskawa automation products. It is specifically used in their product lines, most notably the Sigma-series and E-V series. You will find this error code documented in the technical manuals for:
