Product Description:

The 8I76T400037.00-000 inverter is manufactured by B&R Automation as part of the 8I7 ACOPOS Inverters series. This three-phase device functions as a variable-frequency power stage for compatible motors. It supplies up to 0.37 kW of mechanical output, allowing precise speed and torque control in automated assembly lines and conveyor segments.

During steady operation, the inverter delivers a nominal output current of 1.5 A, which supports the stated shaft output without exceeding thermal limits. When connected to a 500 VAC supply, its apparent power draw is 1.2 kVA, while a 380 VAC line results in a mains current of 1.8 A, making it suitable for light-duty axes. The internal controller switches the IGBTs at a nominal clock frequency of 4 kHz, balancing acoustic noise and efficiency, and six discrete digital inputs allow direct connection of limit switches or sensors. An integrated EMC filter curtails conducted emissions, and communication to the machine network is handled through Powerlink Type 3. Fault containment is enhanced by a short-circuit rating of 5 kA and by the requirement that any regeneration circuit keeps brake resistance above 80 Ω. The housing carries an IP20 rating for cabinet-mounted use.

An initial inrush of 10 A must be accommodated by the upstream circuit breakers, and the logic section requires a separate 24 Vdc feed that draws 1.1 A, keeping the control electronics active during main-power faults. For dynamic events, the drive can pass a transient motor phase current of 2.3 A for 60 s, giving extra torque during acceleration before settling to the continuous level noted earlier. Internal losses remain modest at 27 W, so panel ventilation rather than dedicated cooling is normally adequate. The assembled unit weighs only 2.5 kg, minimizing load on DIN rails in compact cabinets.
