Product Description:
The 8BVI0220HWD0.000-1 is a servo controller module produced by B&R Automation within the 8BVI Servo Controllers series. Designed to operate two-axis or multi-axis drives, it converts DC bus energy into regulated three-phase outputs for precision motion tasks. In automated cells, this unit links the machine control PLC to the servomotors, providing the power stage, switching functions, and an integrated brake supply for coordinated positioning and speed control.
Each output channel can deliver a continuous phase current of 22 Aeff, allowing the drive to sustain rated torque on larger synchronous motors during constant production loads. At that current, the module can supply up to 16 kW per motor, which suits mid-range packaging, printing, and material-forming axes. Short acceleration bursts are covered by a peak envelope of 55 Aeff, so inertia mismatches or start-stop cycles do not trip the current limit. The internal IGBT bridge commutates at 5 kHz, balancing switching losses with acceptable acoustic noise, while its control loop can modulate the fundamental output up to 598 Hz for high-speed spindle or linear motor applications. An integrated 250 mA slow-blow fuse guards the logic supply against overcurrent faults.
The housing carries an IP20 rating, so it is intended for closed electrical enclosures where forced air removes heat from the 263 mm-deep unit. Reliable operation is specified up to 4000 m altitude without current derating, making the unit suitable for elevated sites. Energy storage on the DC link is handled by 1320 µF of electrolytic capacitance, and residual charge is bled by a 0.44 µF discharge network to meet safety time requirements. Motor leads may extend to 25 m per axis, and the built-in brake driver provides 2.1 A through a 0.3 Ω coil to secure vertical loads when motion stops. Overall dimensions of 317 mm in height and 106.5 mm in width support compact cabinet layouts.
