When the A910 code populates on your digital operator, it is usually triggered by one of three main catalysts: 1. Cumulative Fan Operating Time Reached
The clock on the wall of the automotive plant read 2:14 AM when the line stuttered.
Because the drive keeps running during an A910 alarm, it can be tempting to ignore it. Doing so carries heavy risks:
Verify that the upper limit is higher than or equal to the lower limit. Step 4: Perform a Parameter Reset (If Necessary) yaskawa error code a910
When you see the A910 warning, follow this systematic approach to identify the source:
In the high-stakes world of industrial automation, downtime is costly. When a Yaskawa drive—whether from the V1000, J1000, U1000, GA700, or A1000 series—halts production with , it signals a specific power-related fault. While this alarm can be alarming to operators, understanding its root causes is the first step toward rapid resolution.
Squeeze the retention tabs on the fan housing, disconnect the plug-and-play power cable, and slide the old fan out. When the A910 code populates on your digital
Change the value to (this resets the accumulated operating time percentage back to zero). Press ENTER on the keypad to save.
Ensure the target tuning speed is lower than the maximum rated frequency.
If you need more specific guidance for your particular drive model or application, please provide any additional details, and I'll do my best to help further. Doing so carries heavy risks: Verify that the
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.
Specifically, the Yaskawa manual defines the A910 warning as: . It indicates that the servomotor is drawing excessive current and operating at a critically high load. This specific warning serves as the final warning before the system triggers an overload alarm (specifically A.710 or A.720 ). Think of it as the "check engine" light before the engine seizes.
He didn't even have to reset the drive; because A.910 is a warning, it cleared itself once the operating conditions returned to normal. The conveyor sped back up, the "Ghost" was gone, and the factory floor returned to its steady, industrial hum. Technical Summary of A.910 🛠️ Overload Warning Severity
For drives powered by separate control terminals (e.g., S1, S2 for 24VDC), an unstable control supply can sometimes miscommunicate with the main board, indirectly causing a main circuit undervoltage detection logic fault.
Rarely, a corrupted parameter set (especially after a poor upload/download operation) can misconfigure the current offset auto-calibration routine. This is more common after battery-backed memory failures.
