What the order code says about the cabinet you receive
The ABB ACS800-U4-0300-5+E210+P901 is an AC cabinet drive built on the ACS800-U4 platform, with +E210 and +P901 listed as factory option codes that alter the cabinet content beyond the base 0300-5 frame rating. Quoting the suffix string exactly is what makes the BOM line reproducible — a missing +E210 or +P901 ships a different cabinet. At 199.58 kgs the cabinet is a rigged-in unit, not a wall-mount module. Plan the lift and the floor loading before delivery, and verify the cabinet footprint against the cell drawings before the rigging crew shows up. It sits in the Motors & Motor Controls > Drives > Motor Drives line as a cabinet-mount industrial drive — the ACS800-U4 generation was the integrated-cabinet tier of the ACS800 family, engineered for line-side filtering, line contactor, and motor-side cabling terminated inside the enclosure rather than left to the panel builder.
Commissioning entry points — what to verify before power-up
First check on arrival is the nameplate string: ACS800-U4-0300-5+E210+P901 must match the purchase order character-for-character, including the +E210 and +P901 suffixes, because each suffix is a separately engineered option that cannot be retrofitted in the field without a factory kit. Default parameter macro on the ACS800 platform is a known commissioning gotcha — verify the active macro against the motor nameplate before the first start command, and confirm the assistant parameter set matches the driven load (DTC, scalar, or a process macro) before running the no-load ID run. Cabinet grounding and EMC practice still applies at this size: bond the cabinet ground bar to the plant ground grid with the shortest practical conductor, land motor cable shields at the cabinet gland plate, and keep the line and motor cable runs physically separated inside the cable basement to keep common-mode noise out of the control wiring.
Same-function siblings — what they actually are and aren't
The ACS550-U1-157A-4 at 89.81 kgs is a different ABB drive family in the same category line, not a functional cross to this ACS800-U4 cabinet.
Sourcing and lifecycle posture
This is an ABB ACS800-U4 cabinet drive listed under the ABB brand — the order code with its option suffix is what gets quoted, and the cabinet is specified into the BOM line by that exact string. For procurement: the drive is sourced to order against an RFQ carrying the full ACS800-U4-0300-5+E210+P901 string including +E210 and +P901, not the base frame alone. Send the RFQ with both option codes called out so the quote matches the BOM line.
