The drive has calculated that the motor current has exceeded the safe limit for a specific amount of time. The electronic thermal overload protection function has triggered a warning.
This is often the first place to look. A faulty electrical connection creates high resistance, which in turn forces the drive to push more current to achieve the desired motion, leading to an overload condition.
Update to firmware v5.08 or later. You can identify your firmware by checking parameter U1-25 (Software Version). If you see "0503" through "0507", you have found the ghost.
The A910 exclusive error code is a specific error message that appears on Yaskawa servo drives or robots when a problem occurs. This error code indicates that there is an issue with the axis's position or movement. When the drive or robot detects an error, it will display the A910 exclusive error code, and the machine will typically shut down to prevent further damage. yaskawa error code a910 exclusive

: Verify that the load is within the motor's rated capacity and that there are no mechanical jams. Check Wiring
Loose or corroded contacts in the main U/V/W motor power cable force the drive to draw imbalanced currents. The drive has calculated that the motor current
High temperatures reduce the efficiency of the electronic components inside the drive housing.
In this article, we will provide an in-depth look at the Yaskawa error code A910 exclusive, its causes, symptoms, and troubleshooting steps. We will also discuss preventive measures to avoid encountering this error code in the future.
To fix this exclusively, you must understand the root physics behind the error. Here are the four definitive causes: If you see "0503" through "0507", you have found the ghost
The load attached to the motor shaft vastly exceeds the rotor's design capacity, resulting in continuous high-current consumption. 3. Electrical and Wiring Defects
The code indicates that the drive's internal algorithms have detected an operation that exceeds the rated overload protection characteristics of the motor. Essentially, the drive is "warning" you that if current conditions continue, the motor or the SERVOPACK will overheat. Common Causes of the A.910 Alarm
: You can often find additional details on current alarms by checking the seven-segment display on the front of the drive or using the software for a more detailed diagnostic readout. or a list of compatible Sigma-7 motor upgrades A.910 fault in Yaskawa Sigma 7 servo drive - Click2Electro
thermal tracking algorithms). When the current draws approach the safety perimeter of the physical hardware, the drive flashes A.910. This design choice allows the system to continue operating while warning the main PLC or local technicians that a critical overload fault—specifically or A.720 (Low Load Continuous Overload) —is imminent if current rates do not drop.
