The ABB 3AXD50000145874 is an ACS880-17-0320A-7 regenerative drive rated 315 kW normal-use output power at 320 A, with a heavy-duty rating of 200 kW / 239 A and a light-overload rating of 250 kW / 307 A. Input voltage is 525 to 690 V three-phase, 48 to 63 Hz. The R8i+R8i frame includes the control unit and carries an IP22 enclosure (NEMA Type 1).
Duty-cycle selection — normal, heavy, or light overload
Three duty ratings let you match the drive to the load profile. Normal use (315 kW / 320 A) covers constant-torque applications. Heavy-duty (200 kW / 239 A) handles higher peak demands — crushers, conveyors, extruders. Light-overload (250 kW / 307 A) suits variable-torque loads like pumps and fans where occasional overload is acceptable. The UL listing mirrors these: 350 Hp normal, 250 Hp heavy-duty, 300 Hp light-overload.
The drive includes 4 analog inputs, 4 analog outputs, 14 digital inputs, and 10 digital outputs. Communication is via CAN; no onboard Industrial Ethernet. Ambient operating temperature is maximum 40 °C, with humidity range 5 to 95% RH. Altitude rating is 1000 m. Sound level is 75 dB(A).
