Product Description:

The 8I64T400220.00X-1 belongs to the 8I6 ACOPOS Inverters series from B&R Automation and is intended for variable-speed control of three-phase motors in automated lines. By converting fixed DC bus energy into adjustable AC output, the unit regulates motor speed, torque, and direction so conveyor, pump, or feeder axes can follow machine commands without mechanical gear changes. This operating method supports controlled acceleration and deceleration, which helps machines respond smoothly to changing process demands. It is suited to installations where electronic speed control replaces fixed-speed motor operation.

In physical terms, the housing measures 184 mm in height, 142 mm in width, and 158 mm in depth, with a mass of 2.35 kg, so it fits tightly packed control cabinets. The power stage is rated for 2.2 kW and drives 3-phase motors without external transformers. Four onboard digital inputs accommodate proximity switches or optical sensors, and the controller samples 4 channels through a front connector. Each logic input presents an impedance of 12.1 kΩ, limiting current draw from field devices, and the inputs are scanned every 4 ms so signal changes can be processed within the drive’s control cycle. The output circuit is configured as a source type, allowing the device to supply 24 V logic to downstream equipment.

The discrete outputs follow fast motion commands and can switch at up to 100 Hz for rapid state changes in indexing or sorting machinery. Safety feedback is aided by the output-monitoring window of 100 µs, within which the drive checks that commanded and actual levels agree, while leakage current is limited to 3 µA to reduce the chance of unintended actuation of sensitive loads. Relay functions use an 8 ms sampling interval, and the electromechanical service life reaches 100,000 cycles before contact wear becomes significant. For networked topologies, the X2x fieldbus tap supplies 1.6 W so that attached sensors can be powered locally without extra terminals.
