The normal-use rating (500 kW / 715 A) applies to variable-torque applications like pumps and fans where current draw drops with speed. If your BOM specifies a 500 kW motor on a pump, the normal-use figure is your match; if it's a crusher or a mixer, use the heavy-duty column.
Integration notes
Frame R11 is a bolted-in module for the multidrive cabinet. It is not a wall-mount unit — plan for a cabinet with a gland plate and busbar connections rated for 715 A continuous. The IP20 open-type enclosure means it is for indoor use in a clean, dry electrical room; no washdown or dust tolerance. Position control is built in, so you can skip an external encoder interface card for applications like cut-to-length or indexing.
