Product Description:
The 8I74T400400.010-1 is an AC inverter produced by B & R Automation for the 8I7 ACOPOS Inverters series. It converts a fixed 380 V three-phase supply into a regulated output so that the speed, torque, and direction of an induction or permanent-magnet motor can be controlled from the plant controller through the integrated Powerlink bus. The unit acts as the power interface that lets automated packaging lines, material-handling systems, and similar equipment adjust motion profiles without mechanical gear shifting.
At the power stage, the inverter can deliver 4 kW of mechanical shaft power to the connected motor, while its apparent power reaches 9.1 kVA, reflecting the total volt-ampere demand on the feeder. Steady-state operation is supported by a nominal output current of 9.5 A, and the unit draws 13.7 A from a 380 V AC mains network at rated load. The electronics are housed in an IP20 enclosure suitable for ventilated control cabinets. During continuous service, the converter releases 125 W of heat, so cabinet airflow must be sized accordingly. Its housing measures 60 mm wide, 245 mm deep, and 317 mm high, allowing several inverters to be placed side by side. Start-up stress is limited by a maximum inrush current of 10 A, and dynamic braking requires an external resistor with a resistance of at least 36 Ω. The inverter has a supply-side short-circuit withstand capacity of 5 kA.
Dynamic load changes are accommodated by a transient current reserve of 15.7 A for two seconds and 14.3 A for sixty seconds, permitting brief acceleration or deceleration peaks without overheating. The drive weighs 2.176 kg, which simplifies handling and installation in a control cabinet without requiring lifting equipment. A Type 2 Powerlink interface supports deterministic cycle times down to the field level, enabling precise coordination of multi-axis machines and process cells.
