Product Description:
The 8BVI0055HWS0.000-1 is a multi-axis servo controller produced by B&R Automation within the 8BVI Servo Controllers series. Designed for cabinet installation, it interfaces with matched synchronous motors to regulate position, speed, and torque in automated machinery such as packaging stations and material-handling gantries. The unit converts DC bus energy into controlled three-phase outputs and includes an internal brake chopper to manage regenerated power during rapid deceleration. This type of controller is typically used where several servo axes must accelerate, decelerate, and hold position in a synchronized manner.
Each motor channel can deliver a continuous current of 7.6 Aeff, allowing sustained torque without thermal derating during normal operation. For transient load surges, the drive can raise its output to 18.9 Aeff, providing short bursts of extra acceleration when the motion profile demands it. The power module supports 5.5 kW of continuous mechanical power per axis, so medium-frame servomotors can run at rated output without external boosters. Pulse-width modulation occurs at a nominal carrier of 5 kHz, balancing acoustic noise and switching losses. The inverter can synthesize output frequencies up to 598 Hz, which suits applications that require elevated electrical frequency. This operating range is useful on servo systems that transition quickly between low-speed positioning and higher-speed travel.
The housing is rated IP20, so the terminals are finger-safe but the unit still requires installation in a closed control cabinet. Reliable service is specified at ambient temperatures up to 55 °C and at elevations up to 4000 m, although operation above standard altitude may require output derating. The integrated brake chopper operates from a DC link of 24 VDC +5.8% / -0%, drawing 1.1 A through a 0.5 Ω resistor and switching up to 0.5 Hz to dissipate excess energy. Physical dimensions are 317 mm high, 53 mm wide, and 263 mm deep for wall mounting, which supports dense drive stacking while leaving space for airflow. The narrow width helps conserve rail space when several power modules are installed side by side.
