H100 Series Inverter Derating Standard (Derating):
The over load rate represents an
acceptable load amount that exceeds rated load, and is expressed as a ratio based on the rated
load and the duration. The overload capacity on the H100 series inverter is 120%/1 min for
normal loads. The current rating differs from the load rating, as it also has an ambient
temperature limit. For derating specifications refer to

Motor Operation
The 2 nd motor operation is used when a single inverter switch operates two motors. Using the 2 nd
motor operation, a parameter for the 2 nd motor is set. The 2 nd motor is operated when a multi-
function terminal input, defined as a 2
nd
motor function, is turned on.
