Yaskawa Error | Code A910

Yaskawa error code A.910 is primarily a rather than a hard fault, indicating an Overload Warning in Yaskawa SERVOPACKs. LK Automation Limited

A910 is not a universal code for all Yaskawa automation products. It is specifically used in their product lines, most notably the Sigma-series and E-V series. You will find this error code documented in the technical manuals for:

After you have taken corrective action, you can clear the warning and resume normal operation.

Three main factors trigger the A910 alarm on a Yaskawa inverter: Fan Operating Time Exceeded yaskawa error code a910

What triggered the error (e.g., auto-tuning, power-up, running a specific program)?

If the torque reference is consistently above 100% of the motor's rated capacity, the load must be reduced. 4. Hardware Inspection

In many cases, the cost of repair (especially for drives under 7.5kW) approaches the cost of a new drive. Yaskawa’s flat-rate repair service or an authorized repair center (e.g., Drives Warehouse, Radwell, or Yaskawa direct) is the recommended route for hardware failure. Yaskawa error code A

: The overload warning level defined in parameter Pn52B is set too low for the current application.

Several factors can trigger this warning, ranging from mechanical fatigue to improper parameter configuration: You will find this error code documented in

Look for parameter or U4-04 (Cooling Fan Life Expectancy) .

In the Yaskawa ecosystem, it is critical to distinguish between an and a Fault (Trip) .
