Yaskawa’s PC-based software provides advanced diagnostic capabilities beyond what the digital operator alone can offer.
Is this error happening during operation, or does it trigger immediately upon powering on or starting a cycle?
Does the alarm happen or during a specific operation (like starting/stopping)? Share public link yaskawa error code a910 exclusive
drives and servopacks are the backbone of modern industrial automation. Known for their robustness and precision, they are the silent workhorses of robotics, CNC machining, and conveyor systems. However, even the most reliable hardware encounters faults. Among the many alphanumeric codes that can flash on a Yaskawa digital operator, Error Code A910 stands out as one of the most misunderstood—and critically important—alerts.
The overload warning level (parameter Pn52B ) may be set too low for the specific application. Share public link drives and servopacks are the
Jammed linear guide rails, unlubricated ball screws, mismatched gearbox ratios, or structural crashes force the motor to draw peak torque indefinitely.
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.

thermal mathematical model based on current draw over time. If the current exceeds the continuous rated limit of the drive-motor pairing, the internal counter accumulates thermal points. 2. The Relationship Between A.910, A.710, and A.720
On most Yaskawa drive platforms—such as the GA700, GA500, A1000, or V1000 series—the prefix . Unlike a "F" (Fault) code which immediately trips the drive and cuts power to the motor, an alarm is generally a warning. When A910 occurs:
If A.910 appears without any motion command, suspect a severe electrical problem—most likely a short circuit in the motor cables or a phase-to-phase short inside the motor itself. Power down immediately and check for visible damage.
