Manually uncouple the servo motor shaft from the mechanical load (e.g., disconnect the coupling or timing belt).
When the calculated thermal load reaches roughly 20% to 50% of the maximum threshold , the drive flashes A.910 on its digital operator. The ALM indicator LED will flash rather than stay solidly lit.
According to Yaskawa technical documentation, the . yaskawa error code a910
If the air filters on your electrical enclosure are clogged, or if the drive's internal heatsink fins are blanketed in dust, the drive cannot dissipate heat effectively. Even if the fan is spinning, the restricted airflow can trigger a pre-overheat alarm categorized under the A910 umbrella. Step-by-Step Guide to Fix Error Code A910
In many modern Yaskawa drives (like the GA700 or A1000), you need to look for parameter .

Before calling for a drive replacement or expensive repair, follow this systematic diagnostic procedure.
Set this parameter to to reset the accumulated operating time counter back to zero.
"Overload," Elias muttered, wiping grease from his hands with a rag. Can’t copy the link right now
Ensure your drive controller firmware is up to date, as newer firmware versions often optimize parameter validation rules.
The most frequent cause of an overload warning is a change in the physical environment of the machinery. If the motor must push harder than it was originally designed to, its current draw spikes. Common culprits include: Misaligned linear guides or ball screws. Lack of lubrication on slides, bearings, or gears. Mechanical jams, debris, or a failing gearbox. 2. Excessive Duty Cycles and Demanding Profiles
Reduce the speed, acceleration, or duty cycle to lower the average load on the motor. Parameter Adjustment:
