Product Description:
The 8BVI0028HCD8.000-1 two-axis servo controller is produced by B&R Automation for the 8BVI Servo Controllers series. It supplies regulated power and processing so paired servo motors follow speed and position commands in industrial automation cells. The unit belongs to the high-voltage class, interfaces with a 24 V service supply, and installs on a cold-plate or feed-through heat sink to move thermal energy into the machine frame. Its two-axis format allows one module to manage coordinated motion on paired servo axes within a compact drive lineup.
This controller delivers a continuous output of 2.8 kW through a nominal DC bus of 750 VDC, which supports stable motor torque during sustained operation. A maximum output frequency of 598 Hz allows fast electrical cycles for high-speed servomotors, while selectable switching edges at 5 / 10 / 20 kHz balance efficiency and acoustic noise. For short accelerations, the power stage can source up to 9.5 Aeff, providing additional headroom above the continuous operating range. Two integrated axis processors distribute bus energy and coordinate current loops so simultaneous motion can be managed within the shared power section.
The power interface is rated for 3.8 A of line current and uses a control-logic input of 25 VDC ±1.6%. Internal energy storage totals 165 µF, which helps smooth regenerated energy and support operation through brief supply dips. Functional safety is built in through the SCBE stop mechanism that de-energizes the phases when a hazardous event is detected. Mechanical dimensions include a width of 53 mm and a height of 317 mm, and the module has a mass of 2.3 kg for dense installation in multi-axis racks. The specified operating range of 5 to 40 °C supports typical cabinet climates, and the cold-plate mounting path lowers internal temperatures without additional fans.
