Product Description:

The 8BVI0330HWS0.000-1 servo controller is produced by B & R Automation and belongs to the 8BVI Servo Controllers series. Acting as the power stage between a shared DC link and a synchronous or induction servo motor, the unit modulates high-energy bus voltage into controllable phase currents so axes can accelerate, position, and decelerate according to PLC commands. By combining motor feedback with its internal current regulators, the controller delivers tightly synchronized motion that is essential in pick-and-place, converting, and machining cells.

Its electrical core is centered on a nominal DC bus of 750 VDC, buffered by 990 µF of link capacitance that absorbs regeneration and supplies peak torque transients. A separate 24 V service feed has 32.9 µF of input capacitance, which helps keep the control electronics active during bus drops. Average power drawn from the common link reaches 24.4 kW, and the inverter can supply a continuous motor phase current of 33 Aeff while switching at a nominal 5 kHz carrier. For high-speed spindles or linear motors, the modulator supports a maximum electrical output frequency of 598 Hz, allowing mechanical speeds well beyond conventional 50/60 Hz drives. These operating values set the thermal and electromagnetic loading that should be considered when sizing cabinet cooling, fusing, and line reactors.

During sustained operation, the controller can deliver 24 kW of mechanical shaft power when paired with a properly rated motor, and short surges up to 83 Aeff cover rapid accelerations or tension spikes. The integrated holding-brake supply provides 4.2 A, eliminating the need for an external relay, and field wiring is permitted up to 25 m between the drive and motor. The control inlet uses 25 VDC with a tolerance of ±1.6% to maintain logic integrity. The housing has an IP20 rating and measures 106.5 mm wide, 263 mm deep, and 317 mm high, making it suitable for standard 300 mm cabinet frames.
