What this unit is and what it drives
The ABB 3AXD50000200054 is a drive control unit in frame size R11, rated for 355 kW normal-use output (503 A) and 315 kW heavy-duty output (460 A) on a 380–500 VAC three-phase supply. The heavy-duty current rating of 460 A is the figure that governs continuous motor load in a constant-torque application — the normal-use 503 A assumes a lighter, variable-torque profile. Light-overload use (492 A) sits between the two, matching the normal-use power of 355 kW but at a slightly lower current.
Open-type enclosure with IP20 protection — suitable for a clean, dry cabinet, not for washdown or dust-laden areas. The unit is rated for operation up to +55 °C ambient and 4000 m altitude without derating; above that, expect to reduce current or forced-cool. Humidity range 5–95% RH non-condensing. Sound pressure at 75 dB(A) under load — noticeable in a small panel room, so factor in ear protection if the drive runs near operators.
Power quality and efficiency
Rated power factor of 1.0 and standby loss of 247 W. The IE2 efficiency level is standard for this class; note the ecodesign exemption — low-harmonic drives are not required to report energy-efficiency data under EU 2019/1781 §2.3.d, so the absence of an IE class on the nameplate is expected, not a defect. Apparent power output is 436 kV·A, which gives a rough sizing guide for the upstream transformer and cabling.
I/O and communications
Built-in analog I/O: 2 inputs, 2 outputs. Digital I/O: 6 inputs, 2 outputs. Communication is CAN-based — no onboard Industrial Ethernet (0 hardware interfaces listed). If the application requires PROFINET, EtherNet/IP, or Modbus TCP, an optional fieldbus adapter module must be added. The control unit includes a lithium coin cell (CR2032, 220 mAh) for real-time clock backup; two cells are fitted, total 6 g.
