UCU control unit types
Different variants of the UCU control units are used in ACS880 drives: UCU-22…24.
These have a different number of converter module connections but are otherwise
identical. The UCU types are interchangeable as long as the number of connections
is sufficient. For example, the UCU-24 can be used as a direct replacement for both
UCU-22 and UCU-23.
