Yaskawa Error Code A910 Exclusive May 2026
Yaskawa Error Code A910 is “exclusive” because it points directly to a hardware failure in the drive’s charging path. While software errors can often be tuned out, A910 demands a hardware-level response. If you see this code, plan for drive replacement or send the unit to a Yaskawa-authorized service center. Do not attempt to bypass the pre-charge circuit – doing so can cause explosive capacitor failure.

Understanding Yaskawa Error Code A910: Exclusive Access
Yaskawa is a well-known Japanese company that specializes in the production of industrial robots, servo drives, and other automation equipment. Their products are widely used in various industries, including manufacturing, automotive, and food processing. However, like any complex machinery, Yaskawa devices can sometimes encounter errors, one of which is the A910 error code. This article aims to provide an in-depth look at the A910 error code, specifically focusing on its meaning, causes, and troubleshooting steps.
What is Yaskawa Error Code A910?
The A910 error code is a specific fault code generated by Yaskawa's servo drives and robots. When this error occurs, it typically indicates that there is an issue related to the system's exclusive access. The error code A910 suggests that the device is experiencing a problem with accessing a particular resource or function that is currently locked or reserved by another process.
Causes of Yaskawa Error Code A910
Several factors can trigger the A910 error code. Some of the most common causes include: yaskawa error code a910 exclusive

Conclusion
The Yaskawa error code A910 is a specific fault code related to exclusive access issues. By understanding the causes and following the troubleshooting steps outlined in this article, users can effectively resolve the error and prevent future occurrences. Regular maintenance, software updates, and monitoring system performance are essential to ensuring the optimal operation of Yaskawa devices. If the issue persists or requires further assistance, it is recommended to contact a Yaskawa support specialist or authorized service provider for additional guidance.
The Yaskawa error code A910 (often displayed as A.910) is an exclusive alarm related to Momentary Power Failure Detection. Yaskawa Error Code A910 is “exclusive” because it
Here is the exclusive, detailed breakdown of what this code means, why it happens, and how to resolve it, specifically for Yaskawa drives (common on V1000, J1000, GA800, GA700, and U1000 series).
Attempt a controlled release
Use the Yaskawa engineering tool
Check network and bus settings
Inspect safety/interlock devices
Resolve lingering logical locks
Firmware and parameter checks
Log and monitor
"Momentary Power Failure" or "Undervoltage during run" The drive detected that the DC bus voltage dropped below the undervoltage detection level while the motor was running.
The drive has calculated that the motor current has exceeded the safe limit for a specific amount of time. The electronic thermal overload protection function has triggered a warning.
This is distinct from code A920 (Overload Trip), which actually stops the drive. A910 is a predictive warning telling you that a trip is imminent if the load does not decrease.
To fix this exclusively, you must understand the root physics behind the error. Here are the four definitive causes:
Unlike general software or parameter-setting errors (e.g., oC, oH, or bUS errors), A910 is exclusive because:
Step A: Verify the Load
Step B: Check Parameter Settings
Step C: Check Carrier Frequency
