Yaskawa Error Code A910 Exclusive Repack May 2026

The Yaskawa error code 0910 (often displayed as A.910) typically indicates a CPU Error. This specific alarm is common on FS100 robot controllers, referring to a failure in the unit. Understanding Alarm 0910

1. The "Zombie Capacitor" Issue (Exclusive Insight)

Yaskawa drives built between 2015-2020 have a known, unpublished sensitivity on the +5V rail that powers the digital operator. As electrolytic capacitors on the control board age, the +5V line can develop high-frequency ripple. The digital operator requires a clean DC signal. Ripple above 50mV peak-to-peak will corrupt the handshake, triggering A910. A standard multimeter will show "5V" and pass the fault, but an oscilloscope reveals the truth. yaskawa error code a910 exclusive

For GA800, GA500, and FP605 Drives

• Cause: High-speed communication polling conflict.
• Exclusive fix: Set parameter H1-xx (Digital Operator Comm Selection) to "0" (Standard), then cycle power. If the fault persists, perform a control board firmware update via USB. Do not use the front SD card slot; it can cause ground loops that trigger A910.

On a Yaskawa Sigma-7 servo drive, the A.910 error code specifically indicates an Overload Warning. This code is exclusive in the sense that it acts as a preemptive alert, appearing before the drive triggers a more severe, machine-stopping alarm like A.710 or A.720. What is Happening?
