Drive rating at a glance
The ABB 3AXD50000145799 is an ACS880-17-0420A-5 regenerative drive rated 250 kW normal-use output (420 A continuous) on a 380-500 VAC three-phase supply. Heavy-duty use drops to 200 kW / 314 A; light-overload use holds at 250 kW / 403 A. The UL side mirrors these currents at 350 Hp normal, 250 Hp heavy-duty, and 300 Hp light-overload. Apparent power sits at 364 kV·A.
What the frame and enclosure tell you
The R8i+R8i frame is a two-cabinet build — one for the supply unit, one for the inverter. IP22 with NEMA 1 means it's indoor-rated, splash-resistant, but not hose-down. Ambient max is 40 °C; derate above that or above 1000 m altitude. The 75 dB(A) sound level is loud enough that ear protection is worth planning for in a quiet control room.
I/O and communications
Four analog inputs and four analog outputs are onboard. Digital I/O counts 14 inputs and 10 outputs. Communication is CAN-based — no onboard Industrial Ethernet, so a fieldbus adapter module is needed for PROFINET or EtherNet/IP. The control unit is included in the delivery.
