Product Description:

The 8CVI045S1HC50.00-1 inverter module is manufactured by B&R Automation and belongs to the 8CVI ACOPOS Inverter Modules series. Intended for decentralized drive architectures, it converts the shared DC-link voltage into a three-phase output that regulates motor speed, torque, and positioning directly on the machine frame. This placement reduces cabinet heat and shortens wiring runs, which helps when axes are distributed across conveyors, packaging stations, and material-handling equipment. Mounting the power electronics close to the motor also keeps installation layouts compact and reduces the length of high-current motor leads.

The module delivers a continuous mechanical output of 1.5 kW while operating from a regulated bus of 750 VDC. Current and voltage feedback are sampled by an internal 12-bit ADC so the control loop can react quickly to command changes and load variation. Output frequency is adjustable up to 598 Hz, and the IGBT bridge runs at a nominal switching rate of 5 kHz to support smooth current control. A 35 µF DC-bus capacitor stores regenerated energy, while a 0.1 µF discharge capacitor damps high-frequency transients. SinCos encoder inputs support vector control, and POWERLINK V1/V2 over 100BASE-T provides deterministic fieldbus communication.

On the motor side, the inverter supports a continuous phase current of 4.5 Aeff and tolerates short-term peaks up to 13.5 Aeff during acceleration or brief impact loads. The cast aluminum housing has an IP65 rating, allowing installation in washdown or dust-laden areas without an added enclosure. Network communication reaches 100 Mbit/s, which supports cycle times suited to high-speed motion tasks. For mains connection points, the design meets Overvoltage Category III requirements, helping protect the electronics against switching surges. That arrangement is useful on machines where the inverter is mounted near moving axes and exposed to airborne dust or routine washdown.
