Product Description:
The 8BVI0055HWD0.000-3 is a servo controller module developed by B & R Automation for the 8BVI Servo Controllers series. Installed inside a control cabinet, it converts energy from the plant’s high-voltage DC link into phase-modulated outputs that drive two synchronous motors. This conversion provides closed-loop speed and torque control for packaging, assembly, and material-handling equipment. In addition to the power stage, the device provides a regulated brake supply so the connected axes can be held safely when motion is disabled.
Its internal DC link is maintained at 750 VDC, providing ample voltage headroom for rapid acceleration. During continuous operation, the controller draws 11.19 kW, while each motor channel is limited to 7.6 A RMS to keep winding temperatures within design limits. For short indexing moves, the phase current can rise to 18.9 A RMS, adding transient torque without exceeding semiconductor ratings. Carrier pulses are switched at a nominal frequency of 5 kHz. This switching strategy creates a smooth sinusoidal waveform that can be modulated up to 598 Hz, allowing high-pole motors to reach elevated mechanical speeds without losing resolution.
The controller’s logic and auxiliary circuits are powered by a supply of 25 VDC ±1.6%, which also feeds the brake driver. To disengage the brake, the unit delivers 1.1 A to the connected brake circuit. A 330 µF bus capacitor stores switching energy, while a 0.2 µF discharge network and 23.5 µF of input filtering suppress voltage spikes and line noise. Real power per axis is capped at 5.5 kW so that thermal loading remains within the heat sink’s operating limits. The housing has an IP20 rating, providing protection against accidental finger contact when the module is installed inside a sealed electrical enclosure.
