Product Description:
The 8BVI0014HWD0.000-1 is a multi-axis servo controller manufactured by B & R Automation and belongs to the 8BVI Servo Controllers series. The unit conditions DC power, generates switching patterns, and supervises feedback loops so that connected servo motors follow commanded position and speed profiles in automated assembly, packaging, and material-handling equipment. Its multi-axis design allows several motion channels to be managed from one controller, which helps keep drive integration compact inside centralized control cabinets.
Each axis can supply a continuous current of 1.9 Aeff, enabling a sustained mechanical output of 1.4 kW before thermal limits are reached. The internal DC bus is held at 750 VDC, which reduces motor cable losses while supporting fast torque changes. Output sine-coded waveforms may reach 598 Hz, and the inverter’s pulse-width modulation is clocked at 5 kHz to lower acoustic noise and current ripple. Under maximum loading, the controller draws 2.91 kW, whereas standby losses stay at 8.8 W to reduce cabinet heating during inactive periods. Two front slots accept plug-in modules for fieldbus, encoder, or I/O expansion so the drive can be adapted to different machine layouts without changing the base unit.
Dynamic reserve is provided by a peak current of 4.7 Aeff per axis, allowing brief acceleration bursts without oversizing the power stage. Logic electronics are supported by a 24 V rail that is smoothed by 23.5 µF of input capacitance and protected with a 250 mA fuse. The main DC link stores energy in 165 µF of capacitance, and a 0.2 µF discharge network helps limit voltage excursions during regenerative braking. The housing is rated IP20, so the unit must be installed inside a closed electrical cabinet. A dedicated 24 VDC holding-brake output with +5.8 %/-0 % tolerance secures axes at rest, and the twin option bays support later functional expansion without changing the mechanical footprint.
