Product Description:
B&R Automation manufactures the 8BVI0440HWS0.000-1 servo controller as a member of the 8BVI Servo Controllers series. The unit interfaces with a shared DC supply and delivers three-phase outputs to synchronous or induction motors, providing the speed, torque, and position response needed for precision axes in packaging, handling, and assembly equipment. By modulating its insulated-gate drivers, the controller links machine-level motion commands to actual shaft rotation and serves as the core of a closed-loop automation cell.
The control electronics run from a panel supply of 25 VDC ±1.6%, allowing logic, relay, and brake functions to stay active during bus discharge or mains loss. For the power stage, a nominal link voltage of 750 VDC is stored in a 990 µF internal capacitor bank that smooths regenerated energy and limits ripple seen by the IGBTs. Under continuous load, the inverter can conduct 44 Aeff to the motor, supporting a mechanical output of 32 kW while the heat sink remains within its rated temperature range. A switching frequency of 5 kHz shapes the sinusoidal waveform and helps reduce acoustic noise. Brake circuitry is available with 4.2 A continuous current and a regulated 24 VDC output so holding brakes can be driven without external hardware.
For rapid indexing, the drive permits output frequencies up to 598 Hz and can source a short-term peak of 88 Aeff to overcome inertial loads. Installation is limited to clean, ventilated enclosures because the housing carries a protection rating of IP20. Motor cables may reach 25 m without exceeding the specified rise times, and the controller housing is 106.5 mm wide, 317 mm high, and 263 mm deep to fit standard 300 mm cabinet depths. These operating limits and dimensions should be considered during enclosure layout and cable routing.
