Product Description:
The 8BVI0330HWSA.000-1 servo controller is built by B&R Automation for the 8BVI Servo Controllers series. It operates as a mains-connected inverter that converts the DC-link voltage of a modular system into sinusoidal phase currents, enabling closed-loop control of large permanent-magnet motors. In an automation line, the unit coordinates axis motion, triggers regenerative braking, and forwards status data to the central PLC so that gantries, winders, or packaging carriages follow programmed profiles within millisecond tolerances.
Rated for a continuous motor phase current of 33 A RMS, the controller can supply substantial amperage without entering thermal foldback. That current supports a continuous shaft output of 24 kW when the connected machine runs at nominal speed. Power is drawn from a shared DC link held at 750 VDC. The internal filter bank provides 990 µF of capacitance to smooth voltage ripple during rapid load changes. With a maximum synthesized output frequency of 598 Hz, the inverter can drive high-speed servomotors whose electrical frequency far exceeds that of standard induction motors. Under steady load, the electronics consume 24.4 kW. A 4.2 A brake channel supplies 24 VDC to control a compatible holding brake.
Pulse-width modulation operates at a nominal switching rate of 5 kHz, balancing acoustic noise and current ripple for precise torque control. For short acceleration bursts, the drive tolerates a peak output of 83 A RMS, providing the additional current needed for fast indexing. The IP20 enclosure protects against accidental contact with hazardous internal components while relying on the cabinet for airflow. The housing is 106.5 mm wide, 317 mm high, and 263 mm deep, allowing several axes to fit on one backplane. Logic circuits use a 250 mA fuse on the 25 VDC rail. The brake line maintains 24 VDC with a positive tolerance of 5.8% for steady clamping.
