Product Description:
B&R Automation builds the 8BVI0880HCS0.004-1 in its 8BVI Servo Controllers series. The unit operates as a closed-loop drive module that shapes the DC bus and modulates phase current for synchronous or induction motors used in automated assembly cells, gantries, and packaging lines. By combining high-power switching devices with integrated 24 V logic support, it supplies both motion control functions and mechanical brake management inside a single chassis, simplifying panel layouts in multi-axis installations. It is suited to coordinated axes that must respond quickly to changing load conditions during automated cycles.
The logic section is powered from a maintenance supply of 25 VDC ±1.6%, and an internal 32.9 µF buffer stabilizes this rail against line dips. Main energy is stored in a 1,980 µF DC link charged to 750 VDC, giving the power stage a substantial energy reserve during regeneration. Under steady load, the controller delivers a continuous armature current of 88 Aeff, which corresponds to 64 kW of shaft power while the device itself draws 65 kW. Acceleration or shock loads can be covered by a peak output of 176 Aeff for short intervals. Current is controlled by a PWM bridge that pulses at a nominal switching frequency of 5 kHz, balancing spectral content with semiconductor losses and motor heating.
Brake control is supplied at 4.2 A with a dedicated 24 V line that is held within +5.8% of nominal to keep spring-applied brakes released during motion. The inverter can synthesize motor voltage up to a fundamental frequency of 598 Hz, allowing high-speed spindles when paired with suitable windings. A cabinet protection level of IP20 requires installation in an enclosed panel free of conductive dust. Mechanical dimensions, most notably a width of 213.5 mm and a height of 317 mm, support dense stacking, and two rear slots accept plug-in option cards for fieldbus or encoder expansion.
