Inverter issues

I’m not an expert in frequency converters, but I ran into a problem. That is, how is it determined whether a frequency converter is under heavy load or light load? I hope someone knowledgeable from Sichuan can answer this.
Classified by the type of load, simple fans and water pumps are generally considered light loads, while loads such as cranes and high-pressure pumps are considered heavy loads
Whether a frequency converter is under heavy load or light load is determined by the loading condition of the equipment. For light loads such as fans, water pumps, conveyor belts, and other applications with low load requirements. Areas with high current loads such as punch presses, cranes, etc., where instantaneous currents are very high
It is related to the load at startup; for example, heavy loads such as heavy oil, while pumps represent light loads. When starting some fans with a load, it is important to choose the appropriate power rating. When selecting the capacity, focus should be on the motor current, with power being a secondary consideration. Some may choose the smaller one at 1.25.
