A: This is a classic symptom of a failing current sensor. Cold temperatures cause semiconductor materials to contract slightly, altering the offset voltage. As the drive warms up, the sensor may drift back into acceptable range temporarily. The sensor still needs replacement.
A: No. If the drive allows you to clear the fault and run, you risk catastrophic motor or drive damage. The current sensors are critical for vector control and overcurrent protection. Ignoring A910 can lead to IGBT failure and a much more expensive repair. yaskawa error code a910
Electrolytic capacitors have a finite lifespan—typically 5 to 10 years under normal operating temperatures. As capacitors dry out, their Equivalent Series Resistance (ESR) rises. They can no longer "hold" the DC voltage steady, especially under fluctuating loads. You will see A910 occur intermittently, often during load transients.
