Product Description:
The 8BVI0220HWSS.000-1 servo controller is part of the 8BVI Servo Controllers series from B&R Automation. Designed for cabinet-mounted motion systems, the unit regulates three-phase servomotors by converting regulated DC-bus energy into high-frequency output pulses. In industrial automation, it provides velocity and torque control for positioning axes, packaging lines, and material-handling cells. Its architecture integrates a gate-drive module, current sensing, and safety-rated shutdown channels, reducing external wiring and simplifying setup.
It delivers a continuous motor current of 22 Aeff, so it can drive rated loads without thermal derating under steady-duty conditions. The internal DC link is maintained at 750 VDC, providing a wide voltage range for rapid torque transients while keeping conduction losses low. A nominal switching frequency of 5 kHz provides the required pulse-width modulation resolution and limits audible noise from the motor windings. For high-speed spindles or linear motors, the inverter can modulate up to 598 Hz at the output terminals, permitting mechanical speeds well above those of standard 50 or 60 Hz machines. Momentary overload events are handled by a peak phase current of 55 Aeff, which supports aggressive acceleration profiles without triggering a protective shutdown.
Continuous electrical throughput reaches 16 kW, and energy buffering is assisted by a DC-bus capacitance of 495 µF, which smooths regenerative power returned during deceleration. The controller remains operational at ambient temperatures up to 55 °C, indicating the effectiveness of its forced-air cooling channel in a sealed cabinet. The housing measures 106.5 mm in width, 263 mm in depth, and 317 mm in height, allowing side-by-side mounting with other 8BVI modules. Installations must also maintain the maximum motor cable length of 25 m. The family uses a 32.9 µF input filter to condition incoming electrical power.
