Yaskawa Error Code A910 〈2025〉

Before performing any physical diagnostics, and wait at least 5 to 10 minutes for the internal DC bus capacitors to fully discharge. Verify there is zero voltage at the incoming terminals (L1, L2, L3) and the DC terminals (+, -) using a properly rated multimeter.

The drive uses one or three current sensors (depending on phase count). Over time, these sensors can drift due to thermal stress, electrical spikes, or simply age. When the sensor outputs a non-zero signal at zero current, the A910 alarm trips. yaskawa error code a910

Ensure that your application command values do not exceed the safety limits programmed into the drive.

Inspect the power cables running from terminals U, V, and W to the motor for insulation damage or sharp bends. Before performing any physical diagnostics, and wait at

A mechanical part is jammed, stuck, or binding, forcing the motor to work harder than normal.

: Ensure all motor and encoder cable connections are secure and correctly pinned. This link or copies made by others cannot be deleted

Keep track of the age of mechanical couplers and gearboxes. As gearboxes wear out internally, their efficiency drops, shifting the mechanical burden directly onto the Yaskawa motor.

Follow these sequential steps to diagnose and clear the A910 error code from your Yaskawa digital operator. Step 1: Verify Motor Nameplate Data

Gently spin the fan blades with a non-conductive tool. The blade should rotate freely without resistance or grinding noises. If it feels stiff or gritty, the bearings are shot. Step 2: Clean the Cooling Assembly
