What shows up on the dock
The ABB ACS800-104-0320-3+E205+V991 is an industrial motor drive on the ACS800 platform, coded under Motors & Motor Controls › Drives › Motor Drives. The label suffix (+E205 +V991) sits on the same ACS800-104-0320-3 base, so a buyer cross-referencing the code is looking at the configured variant rather than a separate catalog line. Unit mass on this listing is 58.97 kg — a two-person lift, and the panel has to carry it. Verify backplane and enclosure rating against that figure before specifying the slot.
Commissioning frame of mind
ACS800-platform drives run their commissioning tool over the panel port, so the engineer on the FAT bench should confirm firmware revision against the site backup before flashing parameters. ACS800 units are well known to integrator teams for throwing nuisance faults at startup when an old parameter file gets pushed onto newer control firmware — load the matching drive firmware revision, then the parameter set, then walk the I/O map.
