Product Description:
The 8BVI0330HWSS.000-1 is a servo controller built by B&R Automation for the 8BVI Servo Controllers series. In an automation cell, it links a DC bus to a synchronous motor and modulates energy so that positioning, speed, and torque match instructions from the machine PLC. By combining power conversion and motion control in a single IP-rated housing, the unit simplifies cabinet wiring for multi-axis assemblies. This integrated arrangement also reduces the number of separate components required between the power source, controller, and connected motor.
The power stage operates from a DC link of 750 VDC, buffered by a bus capacitance of 990 µF that smooths line-side ripple and stores regenerated energy. A fused 24 V auxiliary output limited to 250 mA supplies panel sensors, while the incoming control rail remains within 25 VDC ±1.6% and is stabilized by 32.9 µF of input capacitance. Inside the inverter, insulated-gate modules chop the bus at a switching frequency of 5 kHz. This carrier supports a maximum fundamental output frequency of 598 Hz for high-speed servo motors. During acceleration, the current can reach a peak of 83 A RMS. The drive dissipates residual charge through a 0.22 µF discharge network to reduce voltage after power is removed.
On the motor side, the continuous phase current is 33 A RMS, and the rated motor output is 24 kW. Overall electrical demand reaches 24.4 kW under full regeneration. A built-in brake supply delivers 4.2 A across 0.15 Ω of coil resistance, providing power for a holding brake on vertical axes. The assembly has an IP20 ingress protection rating and may be installed at elevations up to 4,000 m without derating, provided adequate ambient cooling is maintained. Protective fusing and the discharge network help control electrical energy during normal operation and after shutdown. Appropriate airflow around the housing allows the switching devices to remain within their permitted thermal range during sustained operation.
