Product Description:
B&R Automation produces the 8BVI0110HWS0.000-1 as part of its 8BVI Servo Controllers series. The device is a three-phase inverter that converts a shared DC bus into precisely timed phase currents for brushless servo motors used in packaging machines, pick-and-place gantries, and other motion cells. Separate low-voltage logic and high-voltage power stages allow safe service access while keeping the high-energy section energized for neighboring axes. This layout suits modular drive cabinets where several axes operate from the same DC bus.
The power stage can supply a continuous motor current of 15.1 Aeff, which is the steady-state line current available to the connected axis. That current corresponds to a continuous mechanical output of 11 kW, allowing medium-sized servo motors to sustain demanding duty cycles. Incoming logic power is supplied from a nominal 24 V source, and the input is rated at 25 VDC ±1.6% with 23.5 µF of input capacitance to stabilize the low-voltage control electronics during load transients. The main energy reservoir is a 330 µF DC bus charged to 750 VDC, supporting a bus consumption of 11.2 kW while limiting ripple with a 0.14 µF discharge network. A maximum output frequency of 598 Hz allows the controller to run high-speed motors, and the 2.1 A brake output delivers 24 VDC (+5.8%/−0%) to release or engage external holding brakes when commanded.
Dynamic events are handled by a nominal switching frequency of 5 kHz, which sets the carrier bandwidth for the IGBT bridge and influences audible noise and current ripple. During rapid accelerations, the drive can deliver a peak phase current of 37.7 Aeff, giving additional headroom above the continuous rating for short torque bursts. The housing carries a protection grade of IP20, so it must be installed inside a panel but does not require extra gasketing against dust. With a height of 317 mm and a width of 53 mm, it fits narrow controller bays while leaving airflow paths around adjacent modules.
