Drive rating and duty cycles
The ABB 3AXD50000145904 is an ACS880-17-0660A-7 regenerative drive rated for 630 kW normal use at 660 A, with heavy-duty output of 450 kW at 494 A and light-overload output of 560 kW at 634 A. Input voltage range is 525 to 690 V three-phase at 48 to 63 Hz. The drive is exempt from EU ecodesign requirements (Regulation EU/2019/1781, §2.3.c) because regenerative drives return energy to the line rather than dissipating it as heat.
IP22 protection with NEMA Type 1 enclosure, rated for a maximum 40 °C ambient and 5 to 95 % relative humidity. Altitude limit is 1000 m without derating. The frame size is 2xR8i+2xR8i — a large multi-module cabinet, not a standalone drive. Sound pressure level is 77 dB(A).
The drive includes 4 analog inputs, 4 analog outputs, 14 digital inputs, and 10 digital outputs. Communication is CAN-based; no onboard Industrial Ethernet interface. A control unit is included. The battery pack uses two BR2032 lithium coin cells (3 V, 200 mAh each) for real-time clock backup.
