While this isn't a hard "fault" that will immediately trip the drive, it is an urgent alert that the system is operating dangerously close to its thermal or mechanical limits. Ignoring an A.910 warning typically leads to an (Overload: High Load) or A.720 (Overload: Low Load) fault, which will shut down your motor to prevent permanent damage. What Does the A.910 Error Code Mean?
Before diving into software, check the hardware. Disconnect the motor from the load and rotate the shaft by hand. If you feel resistance or "binding," the problem is mechanical. Lubricate joints, check belt tension, and ensure there are no obstructions in the machinery. 2. Verify Wiring Integrity
When troubleshooting a machine actively displaying an A.910 code, execute these standard diagnostic steps:
By default, the A.910 warning is often set to trigger when the load reaches 20% of the maximum overload capacity. If your application naturally runs "hot" but within safe limits, you may need to increase the value of (Overload Warning Level) to a more suitable percentage. 5.

If you encounter this error, follow these standard diagnostic steps:
What is the of your Yaskawa drive (e.g., GA700, A1000)?
If the load condition persists despite the warning, the drive will eventually trip with a A.710 (Overload) or A.720 (Inertia Overload) alarm. Causes of the A910 Overload Warning While this isn't a hard "fault" that will
In many factory-default configurations, the parameter is set to a conservative threshold (such as 20% of the maximum thermal capacity). Under highly dynamic duty cycles with frequent acceleration and deceleration, the system will trigger the warning prematurely despite being well within safe operating limits.
Overload Warning (Electronic Thermal O/L) Severity: Warning / Alarm (The drive will typically continue to operate unless parameter settings force a stop, but the fault must be cleared to reset the monitor).

: This triggers when the system reaches a specific percentage (typically 20% to 100% based on user configuration) of the ultimate shutdown limit. The drive continues to run, but the digital operator flashes the code, and a assigned digital output trips.
: Rapid acceleration/deceleration cycles or continuous high-torque operation can exceed the drive's overload protection characteristics. Parameter Configuration Overload Warning Level (Pn52B)
