Yaskawa Error Code A910

“Sal, I need a lift,” she said.

Incorrect wiring or faulty contacts between the servomotor and the encoder. Parameter Settings: The overload warning level (specifically parameter

If you see repeatedly during deceleration, you actually might have an overvoltage (A900) problem that is causing the DC bus to oscillate and undershoot.

The drive was seeing the power drop, throwing A910 as a warning: “Don’t even think about starting the motor. I don’t have the muscle.” yaskawa error code a910

If the machine's programming has been altered to increase throughput, the motor may not have enough downtime to cool down. High acceleration rates, aggressive deceleration profiles, or a high number of starts and stops per minute will rapidly build up thermal energy. 3. Faulty Wiring or Poor Contact Issues

Unlike critical alarms, the servo amplifier will continue running the motor while this warning is active. This design allows the controlling PLC or automation system to finish its current cycle or execute a controlled deceleration routine rather than triggering an abrupt, damaging emergency stop. Primary Causes of Yaskawa Error Code A910

Cross-reference the parameters entered into the drive with the actual physical nameplate on the motor. Check parameter (Motor Rated Current). Check parameter E1-04 (Maximum Output Frequency). “Sal, I need a lift,” she said

If a production line is sped up beyond original design specifications, the motor has less time to rest between moves. This continuous operation drives up the root-mean-square (RMS) current, triggering the thermal warning. 3. Misaligned Gain Tuning

The drive constantly monitors the DC bus voltage. If that voltage dips below the drive’s minimum operating threshold, it cannot guarantee proper output to the motor. This triggers .

Using an encoder type that does not match the SERVOPACK's configuration or settings. The drive was seeing the power drop, throwing

Look for jams, binding, or lack of lubrication.

The A910 warning is usually a symptom of a root problem, not the problem itself. The most common causes include:

is an undervoltage alarm of the main DC bus. While it can be a protective response to a brief power glitch, it often points to serious infrastructure issues: loose wires, undersized feeders, aging capacitors, or a failing soft-charge circuit.
