Product Description:
The 8BVI0220HWDS.000-3 is a dual-axis servo controller manufactured by B & R Automation for the 8BVI Servo Controllers series. It governs current loops and commutation for two brushless motors, converting low-voltage DC power into high-frequency, three-phase waveforms that execute positioning and speed commands issued by the machine PLC. Mounted on a DIN rail inside an IP-rated cabinet, the unit supports integrated brake control and the axis coordination required for pick-and-place modules, conveyors, and multistation assembly cells.
Each motor channel can supply a continuous current of 22 Aeff, allowing the heat sink to remain within thermal limits during continuous operation. For rapid acceleration or sudden load changes, the current rises momentarily to 55 Aeff, allowing short bursts of torque without saturating the power stage. Sustained mechanical output reaches 16 kW per axis, making the controller suitable for mid-frame servo motors used in packaging lines. Pulse-width modulation occurs at a nominal switching frequency of 5 kHz, balancing harmonic content with drive efficiency. The DC link contains 1320 µF of capacitance, reducing ripple and protecting the IGBTs from overvoltage during regenerative events. A dedicated brake circuit delivers 2.1 A through a 0.3 Ω coil so that holding brakes release reliably at power-up. The enclosure is 317 mm high and 106.5 mm wide, permitting dense stacking inside standard control cabinets with a depth of 300 mm.
Total electrical draw for both axes is limited to 37 kW, which must be considered when sizing cabinet wiring and thermal management systems. The control electronics require a stabilized bus of 25 VDC ±1.6%, supporting logic integrity during brownout conditions. The drive can produce an output frequency of up to 598 Hz for high-speed spindle or linear motor applications. It can operate at installation elevations ranging from sea level to 4,000 m. The enclosure has an IP20 protection rating, so the surrounding cabinet must provide additional protection against dust and moisture. The controller can operate at an internal ambient temperature of up to 55 °C. Its mass of 5.7 kg places a moderate load on the mounting panel.
