Master Guide: Troubleshooting the Yaskawa A910 Error Code The that occurs on modern servo drive systems. It explicitly indicates that the Yaskawa SERVOPACK or robot controller has detected early stages of motor overload, preceding a hard critical fault.
If you operate industrial automation equipment, you’ve likely encountered the distinctive red digital display of a Yaskawa servo drive flashing an error code. Among the most common and concerning of these is . Understanding and resolving this warning is critical to keeping your production line moving efficiently.
: Triggers if the motor runs continuously under a mild torque load exceeding ratings for an extended period. The servo turns off immediately. Hardware-Specific Variations: Sigma-7 vs. Sigma-3
(Overload Warning Level) dictates exact trigger points. yaskawa error code a910 exclusive
Another frequent trigger for A.910 is simply pushing the motor system too hard. This can involve setting a motor acceleration rate too high for the system's inertia or commanding a speed that cannot be physically achieved with the available torque. In either case, the motor ends up operating beyond its "overload protection characteristics" for extended periods, triggering the warning as a protective measure. You may need to lower the acceleration rate or use a filter like Pn217 (Average Position Reference Movement Time) to smooth out the motion reference.
Field service reports confirm this as a frequent culprit. A manual inspection test involves rotating the ball screw by hand for 2–3 clockwise turns, then counterclockwise for 2–3 turns, carefully observing for any sticking or resistance along the travel path.
In diagnostic settings, swapping the suspect drive’s power supply cable with a known-good drive can help isolate whether a wiring issue exists. Master Guide: Troubleshooting the Yaskawa A910 Error Code
