The Yaskawa error code A.910 is an Overload Warning (pre-alarm) primarily found in Sigma-series servo drives (Sigma-3, Sigma-5, and Sigma-7). It serves as a precursor to more severe faults like A.710 (instantaneous overload) or A.720 (continuous overload). Error Summary
(Overload Warning Level). Adjusting this value can provide more headroom if the application naturally runs close to the limit without actually risking damage. Check Environmental Conditions
- Compare this value to the motor nameplate rated current.
- Issue: If L3-02 is set lower than the nameplate, the drive restricts the motor prematurely.
- Fix: Adjust L3-02 to match the motor nameplate exactly.
Check physical connections
