Product Description:

The 8BVI0028HCS0.000-1 is a servo controller produced by B&R Automation for the 8BVI Servo Controllers series. It regulates three-phase servomotors in automated machines, converting the plant’s DC supply into pulse-width-modulated outputs that match commanded torque and speed profiles. By integrating current regulation, bus management, and brake control in a single unit, the device simplifies panel wiring and supports coordinated motion in packaging, printing, and material-handling equipment. This arrangement helps the controller maintain stable axis behavior during acceleration, deceleration, and rapid load changes.

The controller can supply a continuous motor current of 3.8 Aeff, which corresponds to a sustained shaft load of 2.8 kW. A DC bus rated at 750 VDC stores energy in a bank with an aggregate capacitance of 165 µF, which helps stabilize the link voltage during load transients. Additional 24 V logic power is filtered by 23.5 µF of input capacitance so the control electronics remain less affected by supply ripple. During regeneration, the 0.14 µF discharge capacitor limits dv/dt to protect adjacent modules. Maximum output frequency reaches 598 Hz, and nominal switching occurs at 5 kHz to balance acoustic noise and semiconductor losses. The unit draws 2.87 kW of continuous power from the mains and permits motor cable lengths up to 25 m at the stated carrier frequency.

An enclosure rating of IP20 permits installation inside a closed cabinet with forced ventilation. For dynamic holding tasks, the integrated brake channel delivers 1.1 A through the coil, handles up to 1.5 W·s of energy per stop, and allows release cycles up to 0.5 Hz against a resistance of 0.5 Ω. Short bursts up to 9.5 Aeff provide peak torque during acceleration without triggering overcurrent trips. These operating values support applications that need brief overload capability while keeping normal current demand within the controller’s continuous range.
