Overview

The ABB BDFC-01C Fan Control Panel is a sophisticated digital frequency converter designed specifically for use with the ACS880 (frame R8i) converter module hardware. This versatile control board offers exceptional flexibility by allowing multiple modules to be connected in parallel, thus enhancing braking power. The BDFC-01C ensures precise and efficient braking control within drive systems, making it an essential component for demanding industrial applications.

Functional Highlights

This control panel operates using a UCU-x2 control unit, managing the connections between the DC side of the converter and the AC phase connections of the brake resistor. The BDFC-01C plays a crucial role in regulating the pulse length of the upper-leg IGBTs, which controls the duration that the resistors are linked to the DC link. Typically, the modulation frequency operates at 1 kHz with a 120-degree phase shift to minimize DC voltage ripple.

Moreover, the BDFC-01C continuously monitors critical operational parameters such as phase currents, DC voltage, module temperatures, and ambient temperatures. This monitoring capability allows the system to protect the brake unit from various potential faults, including IGBT short circuits, overcurrent situations, phase loss, and current asymmetry.

In addition, the fan control panel guarantees reliable operation by providing safeguards against DC overvoltage, IGBT overtemperature, module overtemperature, and resistor overtemperature. These protective features ensure that the braking system remains safe and dependable throughout its operation.
