Code A910 Exclusive: Yaskawa Error

Because it is a warning, A.910 typically clears automatically once the overload condition is eliminated. In some cases, you may need to cycle power to the SERVOPACK after correcting the underlying issue.

Think of A.910 as your servo drive’s equivalent of a car’s temperature gauge entering the red zone: you still have time to pull over and investigate before the engine overheats and shuts down completely.

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.

sets the current threshold as a percentage of the motor’s rated current at which the A.910 warning triggers. The default setting is typically 100%, meaning the warning appears when current reaches or exceeds the motor’s rated continuous current. Because it is a warning, A

Using Yaskawa’s SigmaWin+ software or the digital operator, navigate to the (Overload Warning Level) parameter. Compare the setting against the application’s normal operating current.

(Overload Warning Level) dictates exact trigger points. On a Yaskawa Sigma-7 servo drive, the specifically
