Product Description:
The 8I66T400750.0P-000 is an adjustable-frequency inverter module produced by B&R Automation for use in the 8I6 ACOPOS Inverters series. The unit converts fixed mains power into a variable AC output so servo and induction motors in automated machinery can follow precise speed and torque commands. Integrated use in a distributed control architecture lets the control system match motor behavior to process demands while maintaining electrical isolation and limiting the effect of regenerative energy on upstream supplies. Because the output frequency and voltage are controlled electronically, the drive can support smooth acceleration, deceleration, and speed holding across changing load conditions. It is suited for packaging lines, material-handling axes, and compact machine tools where panel space and modular cabling are limited.
The housing extends 178 mm from the mounting surface, spans 150 mm across the front, and has a height of 232 mm. These dimensions help determine the clearances needed around the drive for wiring and cooling air. The front width and depth also affect cable bend space and the distance to nearby components in tightly packed enclosures. Its output bridge is rated for 7.5 kW, allowing it to run medium-power pumps, conveyors, or extruder screws without external step-up gearing. Connection to the facility mains is made through a 3-phase feed so line current is shared across the supply and power delivery remains consistent in standard industrial installations.
The mounting template uses a vertical pitch of 210 mm and a horizontal pitch of 130 mm between fixing holes. This spacing helps align the unit on standardized backplates and supports consistent bracket placement. When an optional EMC shield is installed, the overall stack increases to 308 mm, so extra space should be left above the inverter for routing busbars, terminal strips, or ducting. The body mass is 3.5 kg, which keeps handling straightforward during installation and reduces strain on the supporting plate inside compact control cabinets.
