Control units
BCU control unit types
ACS880-07XT uses BCU-02 control unit. There are three variants of the BCU control unit
used in ACS880 drives: BCU-02, BCU-12 and BCU-22. These have a different number of
converter module connections (2, 7 and 12 respectively) but are otherwise identical. The
three BCU types are interchangeable as long as the number of connections is sufficient.
For example, the BCU-22 can be used as a direct replacement for both BCU-02 and BCU-
12.
