Product Description:
The 8I74T400037.010-1 inverter is produced by B & R Automation as part of the 8I7 ACOPOS Inverters series. It converts fixed three-phase mains power into a variable-frequency output for precise speed regulation of AC motors used in conveyors, feeders, and compact assembly stations. By controlling both voltage and frequency, the unit helps coordinate motor torque with process demands and supports energy-efficient, repeatable motion in industrial automation cells.
The electrical envelope starts with an apparent power rating of 1.4 kVA, which is the highest volt-ampere load the drive can draw from the supply. For connected machinery, it supports a motor shaft output of 0.37 kW, making it suitable for low-power axes. Continuous operation is governed by a nominal output current of 1.5 A, so downstream conductors and protection devices must be sized accordingly. During power-up, the DC-link capacitors charge with an inrush current of 10 A, which should be considered when selecting line fusing. The IP20 enclosure provides finger protection but does not seal against dust or moisture, so cabinet mounting is required.
Short-term overload capability reaches 2.3 A for sixty seconds, allowing the drive to accelerate inertia or clear brief mechanical stalls without shutting down. Supply-side fault tolerance is limited to 5 kA, so upstream breakers must interrupt below that level. Internally, the electronics dissipate 27 W of heat that must be removed by control-panel ventilation. Dynamic deceleration can be enhanced by wiring an external braking resistor no lower than 80 Ω. The housing measures 45 mm in width, 245 mm in depth, and 317 mm in height, and it allows a shielded motor-cable run of up to 50 m while maintaining a mass of 1.618 kg for compact panel layouts.
