Yaskawa Error — Code A910 Exclusive

In Yaskawa servo drive systems, the code is classified as an Overload Warning

Power the system back up and execute a low-RPM manual test using the SigmaWin+ diagnostic software tool .

When you encounter an A910 error, follow this systematic approach to identify the root cause. yaskawa error code a910 exclusive

This comprehensive technical guide explains the underlying engineering behind the A.910 warning, addresses its operational causes across different Yaskawa generations, and provides step-by-step diagnostic and resolution pathways. Understanding the A.910 Overload Warning Architecture

: The most common culprit is excessive physical load. Check the motor and connected machinery for physical obstructions, worn parts, or misalignment. Wiring and Contact Faults In Yaskawa servo drive systems, the code is

This alarm serves as a proactive signal. When your drive displays A.910, it means the current load or operating conditions are pushing the servomotor toward its thermal protection threshold. Primary Causes & Diagnostic Steps

| Diagnostic Feature | What It Tells You | |---|---| | | Real-time torque output; helps identify load spikes | | Current Waveform Capture | Reveals phase imbalances and current distortion | | Accumulated Load Ratio | Historical record of how heavily the motor has been loaded over time | | Error Code (603Fh) Object | Displays the most recent alarm/warning code; can be read via fieldbus or SigmaWin+ | Understanding the A

Since this is a CPU error, the board itself may be defective. If the fault persists after power cycling, the unit may require replacement.

: This parameter can be your most powerful tool for tuning the drive's response to your specific application. A low value (e.g., 1%) makes the drive very sensitive, sounding the A.910 warning early, while a high value (e.g., 100%) makes it less sensitive.

If the conditions causing A.910 are ignored and operation continues, the drive will eventually shut down with one of the above errors to protect the motor and internal circuitry. Common Causes Excessive Load
