Product Description:
B&R Automation produces the 8BVI0055HWDS.000-3 servo controller as part of the 8BVI Servo Controllers series. The device converts power from a shared DC bus into pulse-width-modulated outputs that drive synchronous or induction motors, making it suitable for coordinated motion axes in packaging, assembly, and material-handling machinery. A 25 VDC ±1.6% logic supply powers its internal processors, while the integrated brake supply simplifies cabinet wiring for motors that require controlled stopping.
Each of the two motor outlets can supply a continuous current of 7.6 Aeff and a peak current of 18.9 Aeff, allowing the controller to manage short acceleration periods without derating. Energy is drawn from a DC bus operating at 750 VDC, and the total continuous power output is rated at 11.19 kW. Each channel can deliver 5.5 kW of mechanical power to its connected motor. Pulse-width modulation supports a maximum output frequency of 598 Hz, allowing operation with high-speed spindles or blowers. Four enable inputs provide independent safety interlocks. A dedicated brake output supplies 24 VDC +5.8%/-0% at 1.1 A per motor for controlled shaft holding when the drive is disabled.
Capacitive energy storage of 330 µF smooths the bus voltage, while an additional 0.2 µF discharge capacitor limits residual energy during shutdown. Carrier signals are switched at a nominal frequency of 5 kHz, balancing acoustic noise with thermal stress on the insulated-gate bipolar transistors. The housing measures 53 × 317 × 263 mm and has an IP20 protection rating, so the module must be installed inside a closed electrical cabinet with forced ventilation. The enclosure protects against contact with hazardous internal components and the entry of solid objects larger than the applicable rating threshold. Two motor connections allow the controller to operate a pair of axes from one module, reducing the amount of panel space required for the drive equipment.
