Product Description:

The 8I64T400300.00X-1 is an AC inverter module produced by B&R Automation within the 8I6 ACOPOS Inverters series. It converts a 500 Vac three-phase supply into a variable voltage and frequency output so that induction or synchronous motors can be driven with speed control and torque regulation in industrial automation cells and machine segments. Designed for cabinet mounting, the unit targets motion axes in packaging, material handling, and processing equipment where compact power stages simplify wiring.

Under a 500 Vac mains supply, the inverter can deliver an apparent power of 7.1 kVA, meaning it can handle the combined real and reactive power demanded by the connected motor. At this voltage, the continuous output current is 7.1 A, and this is the steady-state current limit for continuous operation. When matched with a motor rated at 3 kW, it provides full-load capability across the speed range up to the maximum output frequency of 500 Hz, allowing high-speed spindle operation when required. For short overloads lasting 60 seconds, it can supply 10.7 A, giving additional torque during acceleration or temporary process disturbances. The drive also tolerates short-circuit currents up to 5 kA and uses a minimum external brake resistor of 55 Ω to absorb regenerative energy.

Control performance is supported by a rated switching frequency of 4 kHz in the output stage and an internal counter that resolves position events at 10 kHz. The control loop operates with a minimum cycle time of 400 µs, so fast indexing axes can be synchronized accurately. Four digital inputs accept sensor or limit signals, and unshielded motor cables may run up to 100 m without violating EMC limits. Heat loss in the power semiconductors reaches 125 W, while the overall assembly weighs 2.35 kg and occupies only 142 mm of panel width, which helps in multi-axis cabinet layouts.
