High temperatures reduce the efficiency of the electronic components inside the drive housing.
. This means it often appears when the drive's internal thermal monitoring predicts an upcoming failure based on current load trends. Common Causes and Remedies Description Recommended Action Wiring Faults
Firmware and parameter checks
A multi-function digital output configured for "Alarm" will activate to alert a master PLC or supervisory system. yaskawa error code a910 exclusive
Increased friction forces the servo motor to draw more torque to move the same distance.
To minimize occurrences of the warning in automated facilities, implement the following maintenance steps: A.910 fault in Yaskawa Sigma 7 servo drive - Click2Electro
Troubleshooting the Yaskawa Error Code A.910 (Overload Warning) High temperatures reduce the efficiency of the electronic
If troubleshooting allows, temporarily remove the option card to see if the A910 code disappears. If it does, the option card or its network traffic is the culprit. Step 3: Mitigate Electrical Noise (EMI/RFI)
Monitor the . If it consistently runs near or at 100%, the motor is undersized for the application, or your process has changed.
If the A910 code continuously reappears after cycling power, replacing option cards, and isolating noise, the internal control board may have suffered physical degradation. In this scenario, contact an authorized Yaskawa service center or your local distributor for a board-level diagnostic or replacement. If it does, the option card or its
If you are facing an A.910 error, follow these steps to diagnose and resolve the issue: 1. Inspect the Mechanical System
Ensure the motor and SERVOPACK are properly matched. Yaskawa generally recommends a capacity ratio between 1/4 and 4 for stable operation.
If load has increased permanently, you may need to upsize the motor or servo system. Where possible, reduce the commanded acceleration or deceleration rates to lower peak torque demands.
