Product Description:
The 8BVI0028HWSS.000-1 is a servo controller built by B & R Automation within the 8BVI Servo Controllers series. The unit conditions power from a DC link through a high-frequency PWM stage to regulate brushless servo motors in machinery that requires precise position or torque control. By managing current, voltage, and braking circuits, the controller connects a plant’s low-voltage control section to a 750 VDC power bus, providing an interface between motion commands and mechanical output. Its wall-mounted housing integrates plug-in option slots and field-wiring terminals, helping keep control panels compact.
The logic supply path requires 25 VDC with a tolerance of ±1.6% and is smoothed by an input capacitor rated at 23.5 µF. This combination keeps the microcontroller supply rails stable during inrush or brownout events. Continuous motor phase current reaches 3.8 Aeff, allowing the inverter to deliver 2.8 kW of mechanical power while drawing 2.87 kW internally during steady-state operation. The drive supports electrical frequencies up to 598 Hz, so higher-speed servo motors remain within the vector-control range. A dedicated enable input accepts commands up to 30 VDC, and the brake output supplies 24 VDC with a +5.8% tolerance to engage the motor brake when the axis is idle. Motor leads may extend up to 25 m at the prescribed carrier rate without excessive voltage rise caused by dv/dt.
Power conversion centers on a DC link rated at 750 VDC, complemented by a bulk capacitor bank rated at 165 µF that absorbs regenerated energy from decelerating loads. During fast transients, the inverter can supply a peak phase current of 9.5 Aeff, providing torque reserve beyond the continuous rating. Pulse generation occurs at a switching frequency of 5 kHz, and each command edge reaches the IGBT gates after a rising-edge trigger delay of 52 µs ±0.5 µs. This delay can be accounted for when coordinating synchronized multi-axis motion. Two plug-in module slots accommodate expanded I/O or fieldbus boards. The wall-mounting arrangement channels convective airflow along the heat sink fins without requiring additional ducting.
