What lands on the pallet
The ABB ACS800-104-0580-7+E205+V991 is an AC inverter drive from the ACS800 family, ordered as a single catalog line that bundles two factory option codes — +E205 and +V991 — into the base 0580-7 frame. The drive ships as a cabinet-format module at 58.97 kg, which is a real lift for one person and the kind of mass that drives hoist or trolley choice during unpacking, not panel-layout decisions. Ordering string has to match the BOM exactly, including the plus-codes: a base ACS800-104-0580-7 without +E205+V991 is a different configuration, and a 580-7 suffix on a different ACS800 series frame is a different product.
Where this drive sits in the controls stack
ACS800-series drives are used as the motor-side converter in industrial drive panels, typically between a three-phase supply and an induction or permanent-magnet motor, with parameter macros set through the drive's own keypad or a tools-level upload before the motor is rotated for the first time. For commissioning, the +E205 and +V991 codes are the load-bearing items: those are the option suffixes that fix what the drive ships with — firmware build, I/O and option-module complement, language of the operator panel, application macro. Power up clean, parameterize without drama, and get it through handover testing depends on those codes being on the nameplate exactly as ordered.
Sourcing posture
Spare or replacement buys should pin the full order code including plus-codes on the RFQ; a base-0580 frame without the option codes will not behave as a drop-in for a machine whose control program or feedback option was specified against +E205 and +V991.
