Product Description:

The 8BVI0055HCD8.000-1 servo controller is produced by B & R Automation and belongs to the 8BVI Servo Controllers series. It commands up to two coordinated axes in industrial automation systems, delivering regulated current and voltage to matched servo motors. By converting the plant’s high-voltage DC supply into precise pulse patterns, the unit handles position, velocity, and torque loops needed for packaging machinery, assembly lines, and other motion tasks. It is intended for cold plate or pass-through mounting inside a control cabinet, so thermal energy is transferred directly to the machine frame.

Internally, a DC link rated at 750 VDC stores energy in a bank that totals 330 µF. The high bus voltage lets the controller supply two axes with fast torque rise, while the capacitance smooths regenerated energy during deceleration. Power is modulated by insulated-gate drivers that switch at a nominal 5 kHz, a frequency that balances waveform fidelity against switching losses. The resulting inverter stage can deliver up to 598 Hz of fundamental output, enabling high-speed spindle or linear motor operation. Under continuous load, it provides a phase-balanced current of 7.6 Aeff. Four enable inputs, two trigger inputs, two plug-in option slots, and DNA support allow local interlocks, encoder boards, or fieldbus cards, while the SCBE safety function can shut down each axis independently.

For dynamic moves, the drive can surge to a peak of 18.9 Aeff, matching mechanical inertia without saturation, while its thermal design supports an output of 5.5 kW per controller. The enclosure carries a protection class of IP20, requiring installation in a cabinet while allowing easy access to wiring. The unit is marked as HV, indicating a high-voltage category with increased clearance and creepage rules for systems above 600 V. An integrated heat spreader conducts losses away from power devices and helps maintain semiconductor temperatures during repetitive acceleration cycles.
