Yaskawa Error Code A910 - //top\\

Reduce the speed, acceleration, or duty cycle to lower the average load on the motor. Parameter Adjustment:

If the fan is dirty, use low-pressure dry compressed air (under 30 PSI) or an anti-static brush to clear out the debris. Hold the fan blades steady while blowing air; letting the compressed air spin the fan at hyper-speeds can generate back-EMF and damage the internal drive electronics. Step 3: Check Internal Connections

Inspect the frequency reference upper limit () and lower limit ( d2-02 ).

: Check parameter Pn52B (Overload Warning Level). The default is typically 20%, but it can be adjusted to better suit your operation's normal peaks.

: Inspect the machine for physical obstructions or increased friction. Ensure the load hasn't changed beyond the motor's specifications.

Start with the most fundamental checks:

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. Reduce the speed, acceleration, or duty cycle to

Reduce the operation speed, lower the cycle frequency, or decrease the overall load applied to the motor.

Identify whether the overload occurs during acceleration, deceleration, or constant velocity. 5. Check for Overheating

Unlike critical alarms, the servo amplifier will continue running the motor while this warning is active. This design allows the controlling PLC or automation system to finish its current cycle or execute a controlled deceleration routine rather than triggering an abrupt, damaging emergency stop. Primary Causes of Yaskawa Error Code A910

The default setting for the overload warning detection is 20%, meaning the warning triggers when it is 20% of the way to a full alarm. If the system is operating near its capacity, you may need to adjust these parameters: Step 3: Check Internal Connections Inspect the frequency

The Clearwater Mill recycled cardboard into shipping boxes. The entire plant ran on three shifts, but the 2:00 AM shift—the "graveyard"—was the skeleton crew. It was a world of shadows, hissing pneumatics, and the constant, low hum of Yaskawa drives.

Three main factors trigger the A910 alarm on a Yaskawa inverter: Fan Operating Time Exceeded

The A910 warning points to a misalignment between the mechanical load requirements and the servo system's physical capabilities. The most common causes include: 1. Mechanical Binding and Friction

: Manually inspect the load. Ensure there are no physical obstructions and that all parts are properly lubricated.
