Overload faults include inverter overload and motor overload. It may be due to acceleration time is too short, excessive DC braking, power grid voltage is too low, overloaded and other causes. Generally by extending the acceleration time, extended braking time, check the grid voltage. Overload, the selected motor and inverter can not drag the load, it may be due to poor mechanical lubrication. If the former must be replaced by high-power motors and inverters; the latter will have to overhaul the production machinery.
