The ABB ACS800-U1-0016-5+P901+V944 is a wall-mount AC drive from the ACS800-U1 series, factory optioned with the +P901 and +V944 codes that show up on the nameplate and the PO line. It sits in the motor-drive category, which means it goes on a motor-control panel — the class of part that sits between the supply and an induction or permanent-magnet motor and handles start/stop, speed reference, and fault handling for the connected load. The drive weighs 12.21 kg, which is a one-person lift into a wall-mount cutout but still wants a second pair of hands on the mounting screws.
Option codes — what +P901 and +V944 mean at the BOM line
The +P901 and +V944 suffixes are ABB option codes that ship from the factory pre-wired into the unit; they are not field-installable kits for this series. Because the suffix is part of the orderable string, a buyer sourcing ACS800-U1-0016-5+P901+V944 needs to match the full string — a bare ACS800-U1-0016-5 is a different BOM line. The exact +P901 / +V944 feature content lives in the ABB ACS800 documentation set, not in the storefront row, so a nameplate photo or the ABB configuration print has to ride with the RFQ when a spec question comes up.
