In the world of industrial automation, Yaskawa drives (specifically the GA800, GA700, A1000, and U1000 series) are known for their reliability. However, when an error code appears, it demands immediate attention. Among the various alarms, stands out as particularly “exclusive” due to its specific cause: it is a hardware-exclusive alarm related to the drive’s charging circuit .
Unlike general software or parameter-setting errors (e.g., oC, oH, or bUS errors), A910 is because:
Verify that mode-switching inputs are not toggling too quickly or conflicting. 4. Clear the Error and Reset Settings
First and foremost, the most important fact about code A910 is that it is a , not an alarm. This distinction is critical.
: If you change Pn52B to a higher value to eliminate nuisance A.910 warnings, you are reducing the safety margin for your motor. Increasing Pn52B too much may prevent the A.910 warning from appearing at all, potentially leading to an unexpected A.710 alarm and machine downtime. Adjust this parameter conservatively and with a full understanding of your load cycle. yaskawa error code a910 exclusive
The parameter determines the precise threshold where the A.910 warning triggers. By default, it is set to alert the operator when the motor reaches 20% to 100% of its thermal load capacity. If an engineer sets this value too low, the drive will flag warnings during standard operating conditions. 5. Excessive Cabinet Temperatures
Inspect U, V, and W power leads and the encoder cable for secure seating and damage. Monitor Torque

Inspect the U/V/W power and encoder cables for physical wear, cuts, or sharp bends. Unplug and reseat all connectors to ensure secure contact. In the world of industrial automation, Yaskawa drives
A: No. Do not ignore it. While the warning may clear on a restart, this indicates the drive detected an overload condition during the previous run cycle. The underlying cause—whether mechanical wear, a wiring issue, or an aggressive motion profile—likely still exists and will cause the A.910 warning to return as soon as the demanding operation is repeated. It is always better to thoroughly investigate to prevent an eventual A.710 alarm and unscheduled downtime.
The is a warning that signals an overload condition in a servo drive. Specifically, this code indicates that the motor or drive is operating near its capacity and is at risk of triggering a full "Overload" alarm—either A.710 (instantaneous maximum load) or A.720 (continuous maximum load). What Does the A.910 Error Mean?
Faulty contacts or incorrect motor/encoder wiring can cause the drive to misread the load. Aggressive Duty Cycle:

: Excessive load caused by friction, worn bearings, or physical obstructions in the machine.
An A910 error is rarely an isolated software glitch. It is almost always a physical response to real-world operational stressors across four primary areas: 1. Mechanical Binding and Excessive Loads
: 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.
