Product Description:
B&R Automation produces the 8BVI0028HWD0.000-3 for its 8BVI Servo Controllers series. This unit is a two-channel drive module that supplies regulated current and voltage to synchronous servo motors. In automated machinery, it closes the speed and torque loop between the control PLC and each motor, allowing precise positioning and coordinated motion across multiple axes. By housing two independent inverter sections, it minimizes panel space while maintaining separate feedback paths for each connected axis.
Each inverter channel delivers a continuous phase current of 3.8 Aeff, allowing stable operation for motors with moderate torque demand. For dynamic moves, the drive supports a peak current of 9.5 Aeff for limited durations, giving additional capacity during acceleration. Total heat buildup is limited by a continuous power draw of 5.73 kW, which the cabinet cooling system must dissipate. Internally, a stable DC link rated at 750 VDC feeds both output stages. Its energy storage capacity of 165 µF smooths regenerated energy during deceleration. If the installation altitude rises above 500 m, the available current is reduced by 0.38 Aeff for each additional 1,000 m to protect the switching devices. Each motor channel can continuously absorb 2.8 kW, while the brake circuits capture up to 1.1 A per connection during controlled stops.
Speed control bandwidth is supported by a maximum output frequency of 598 Hz, driven by an insulated-gate bridge that switches at a nominal 5 kHz. Two motor terminals on the front panel permit independent wiring. The module measures 53 mm wide, 263 mm deep, and 317 mm high, allowing installation in high-density enclosures. The housing carries an IP20 rating, so the unit must be mounted inside a closed cabinet where ambient temperatures remain at or below 55 °C. Diagnostic data covering phase currents, bus voltage, and altitude-related derating is routed through the integrated fieldbus interface for remote condition monitoring.
