Product Description:

The 8I64T400550.000-1 is an AC inverter module manufactured by B&R Automation for the 8I6 ACOPOS Inverters series. The device modulates line voltage so that three-phase motors can be driven with variable speed and torque profiles that match machine demand. Integrated support for the X2X real-time network allows the inverter to exchange process data and synchronize motion axes, making it a common component in packaging machines, material-handling stations, and similar automation cells. Within a control cabinet, it occupies modest space while delivering regulated power to induction or permanent-magnet motors.

The power section accepts a three-phase mains feed and can deliver up to 5.5 kW to the connected motor. Event tracking is handled by a 32-bit counter that records encoder or product counts at rates as high as 100 kHz, providing accurate position feedback for high-speed processes. Programmed logic samples the X2X inputs every 4 ms, and the source-configured digital outputs can switch external loads at 100 Hz without additional buffering. A resistive R2 path supports 2 A of continuous energy dissipation during braking events. The inverter’s control electronics operate from the nominal 24 VDC X2X rail, ensuring that drive functions remain stable even when supply margins are tight. This separate control supply also supports communication and logic functions independently of the motor power output.

Panel integration is supported by a height of 184 mm, a width of 142 mm, and a depth of 158 mm. The assembly weighs 2.35 kg, allowing it to be installed without lifting equipment. Logic inputs exhibit 12.1 kΩ of impedance, minimizing the load on proximity switches or PLC output cards. When the outputs are off, leakage is limited to 3 µA, allowing sensitive actuators to remain de-energized. The onboard electronics consume 1.6 W from the X2X backplane, leaving ample reserve for sensors and auxiliary nodes. Its compact dimensions also help preserve cabinet space for neighboring control and power modules.
