Product Description:

The 8BVI0055HWD0.000-1/1 is a multi-axis servo controller released by B&R Automation within the 8BVI Servo Controllers series. In automated machinery, the unit conditions high-voltage DC power and modulates phase currents so that connected synchronous motors follow precise torque, speed, or position commands transmitted from the central PLC. Its two-channel design lets one compact controller manage coordinated motion on paired axes. That layout is useful in equipment where adjacent servo functions must accelerate, index, or track together. By combining power conversion and closed-loop axis control in one module, it supports accurate motion without requiring a separate drive for each small axis group.

Each of the controller’s two drive channels delivers a continuous 7.6 Aeff, which is the sustained phase current available during normal motion profiles. Short bursts are handled by a 18.9 Aeff peak limit, providing current reserve for acceleration and brief load changes. A per-axis power rating of 5.5 kW complements the overall 11.19 kW continuous consumption value. The internal DC link operates at 750 VDC, and its 330 µF capacitor bank smooths regenerated energy between switching events. Carrier modulation occurs at a 5 kHz nominal switching frequency, while the output stage can produce up to 598 Hz fundamental motor frequency for high-speed spindle or linear motor operation.

The housing is 53 mm wide and 317 mm tall, leaving room for convection paths inside an enclosure rated to IP20. The slim housing format also helps conserve panel width in dense control cabinets. Reliable operation is permitted at ambient temperatures up to 55 °C and at installation sites as high as 4000 m. Control electronics use a 25 VDC bus with a ±1.6% tolerance, and the integrated brake supply provides 24 VDC to motor holding brakes with up to 1.1 A of current, so separate brake power is not required.
