Yaskawa Error Code A910 Exclusive Jun 2026

On a Yaskawa Sigma-7 servo drive, the 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?

Log and monitor

The drive has calculated that the motor is working too hard for too long. If you ignore this warning and continue operation, the drive will eventually shut down with a hard alarm to protect the motor from burning out.

If you have a specific Yaskawa model (e.g., GA800, A1000, V1000), reply with the model number and the load type (fan, pump, conveyor, crane) for a tailored parameter list. On a Yaskawa Sigma-7 servo drive, the specifically

Yaskawa drives built between 2015-2020 have a known, unpublished sensitivity on the +5V rail that powers the digital operator.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. Log and monitor The drive has calculated that

Check if panel fans are working or if the heat sink is obstructed.

Turn the main circuit power OFF and then back ON after a few minutes. This can sometimes clear transient initialization errors. Check Hardware Connections:
