What this order code resolves to
The ABB ACS580-01-088A-4+B056+J400 is a 3-phase motor drive from the ACS580-01 general-purpose drive family, ordered here as the 088A-4 frame with the +B056 and +J400 factory option codes appended to the base MPN. It sits in the Motors & Motor Controls category as a Motor Drive, which is the class a buyer expects for wall-mounted industrial VFDs in the ACS580-01 lineup.
Handling note
The drive weighs 28.58 kg, which is enough that the unbox and panel-mount step is a two-person lift and the mounting surface needs to carry that mass without flexing; it is not a selection parameter for the BOM, but it is a real one for the installer.
