Drive ratings and duty selection
The ABB 3AXD50000050414 is an ACS880-17-0271A-7 regenerative drive rated 250 kW normal-use output (271 A) on a 525-690 V three-phase supply. Light-overload use (250 kW, 257 A) mirrors the normal-use power but with a slightly lower current — relevant when the load profile is mostly centrifugal. Frame size R11 and IP22 enclosure mean this drive is built for cabinet mounting in a controlled environment. The 77 dB(A) sound level is worth noting for panel placement near operator stations — not a quiet unit. Ambient temperature is capped at 40 °C, with derating needed above that; altitude is rated to 1000 m without further derating.
Regenerative drive — ecodesign exemption
This regenerative drive is exempt from EU ecodesign efficiency requirements under Regulation EU/2019/1781 §2.3.c. The SCIP number is 82D82DAE-9725-4373-865D-AA949B97DE50 Finland for EU substance reporting.
The control unit includes 2 analog inputs, 2 analog outputs, 7 digital inputs, and 5 digital outputs. Communication is via CAN; there is no onboard Industrial Ethernet interface. The battery information lists two CR2032 lithium coin cells (3 V, 220 mAh each) for real-time-clock backup — factor those into preventive maintenance schedules.
