• For loads (such as fans and pumps) that do not require frequent use of the inverter above the rated
torque, the light load mode can be selected. The rated current of the inverter increases above that of
the heavy load mode, which enables the inverter to drive a motor one size larger. For details on rat-
ed current specifications, refer to 1-3-1 Standard Specifications on page 1-11. The overload capacity
differs as shown in the following table on each specification type.
