Product Description:

The 8I76T401500.0P-000 is an inverter module produced by B & R Automation within the 8I7 ACOPOS Inverters series. Designed for cabinet installation, the unit converts three-phase mains power into a controlled AC output for induction or permanent-magnet motors used in automated machinery, conveyors, and processing lines. In an automation cell, the inverter provides speed, torque, and position control by modulating output voltage and frequency according to programmed motion profiles. This operating method supports repeatable motion in machines where load and speed can change during a cycle.

Its network integration relies on the POWERLINK interface, which permits real-time exchange of setpoints and status data with programmable controllers during synchronized machine operation. The power stage is sized for motors up to 15 kW, delivering a continuous phase current of 33 A and a corresponding apparent power of 30.7 kVA at the drive terminals. Internal control loops operate at a nominal clock frequency of 4 kHz, allowing fine current-vector resolution and rapid dynamic response. With an IP20 rating, the housing requires installation inside a protected enclosure. Its 404 mm height, 180 mm width, and 232 mm depth support compact panel layouts with adjacent modules on a DIN rail or panel.

During energization, the inverter draws an inrush current of 36.7 A, so line contactors and surge limiters must be sized for this short-term demand. Under a normal 500 V AC supply, it carries a mains current of 35.5 A and can deliver transient motor peaks of 49.5 A, while internal fusing is coordinated for a short-circuit withstand of 22 kA on the feeder. Heat produced by the power semiconductors reaches 480 W, so cabinet airflow or liquid cooling must remove that loss to keep component temperatures within range. The aluminum chassis keeps the mass to 8.8 kg, which supports straightforward handling during installation and reduces the load on panel supports.
