YASKAWA ELECTRIC CDBR-4220D - Dynamic Braking Resistor Unit
This YASKAWA ELECTRIC CDBR-4220D unit is an external dynamic braking resistor designed for integration with YASKAWA SERVOPACKs operating in 400VAC class industrial automation systems. Its primary function is to dissipate regenerative energy generated by decelerating servo motors, thereby preventing DC bus overvoltage conditions and ensuring stable, reliable operation of the drive system. This component is essential for applications requiring precise motion control with frequent starts, stops, and rapid deceleration cycles, including robotics, CNC machinery, and material handling systems.
