Product Description:
The 8I64T400400.000-1 inverter is produced by B&R Automation for the 8I6 ACOPOS Inverters series. It converts fixed-frequency three-phase mains power into a variable output that allows a PLC to control motor speed in material-handling, printing, and filling lines. The drive communicates over the X2X bus, so status information, fault reports, and setpoints travel on the same network that coordinates distributed I/O and servo modules. This communication arrangement reduces the number of separate control connections needed within an automated machine.
The enclosure has a cabinet width of 142 mm, a depth of 158 mm, and a height of 184 mm, simplifying side-by-side mounting with other ACOPOS hardware. Its mass of 2.35 kg limits the load placed on the mounting structure, while its continuous output rating of 4 kW supports small to midsize induction motors. The digital output circuit limits leakage current to 3 µA, helping protect downstream optocouplers from unintended activation. Logic inputs have an impedance of 12.1 kΩ, which keeps sensor current requirements low. The mounting holes are spaced 157 mm vertically and 126 mm horizontally to accommodate common back-panel drilling patterns.
A control task can refresh commands every 4 ms, allowing the drive to react quickly to torque or speed requests generated by cam profiles. The drive electronics receive control power through the X2X connector and operate at 24 VDC while consuming 1.6 W, which limits heat generation inside sealed cabinets. The integral relay can switch resistive auxiliary loads of up to 2 A. Its mechanical assembly is rated for 100,000 cycles, making the relay suitable for routine enable or fault-contact duties. The digital outputs use a source topology, allowing compatible actuators to operate without external pull-up resistors.
