Yaskawa Error Code A910 Portable May 2026

The Yaskawa error code A.910 is an Overload Warning that indicates a servo drive is nearing its maximum capacity but has not yet reached a critical shutdown state. It serves as a precursor to more severe overload alarms, specifically A.710 (instantaneous maximum load) or A.720 (continuous maximum load). What Does A.910 Mean?

Specifically, it means the inverter’s internal thermal overload protection logic has calculated that the motor or the inverter itself is being stressed. If the current level remains high, it will eventually trigger a critical fault (usually A911 or A920) and shut down the drive to prevent damage. yaskawa error code a910

Prevention

• Install load monitoring in critical applications (pumps, fans, conveyors).
• Use torque-proving sequences for hoists (ensure torque is present before releasing brake).
• Regularly inspect couplings, belts, and pump prime.

Most Likely Fixes (by probability)

1. Tighten all output terminals – very common.
2. Replace damaged motor cable – especially if flexible cord is used.
3. Repair or replace motor – if winding open or imbalanced.
4. Replace output contactor – worn contacts or coil failure.
5. Replace drive – only if all above are ruled out and alarm remains with known good motor.
