Yaskawa CACR-SK45AAB Robot Controller Servopack

The Yaskawa CACR-SK45AAB Robot Controller SERVOPACK is a medium‑capacity, multi‑axis servo drive controller for Motoman robot systems that regulates position, speed, and torque across connected servo motors. Installed inside the robot control cabinet, it uses closed‑loop servo control with encoder feedback to deliver high‑precision, coordinated motion across multiple axes by interfacing with the robot CPU, axes drives, and servo motors. It supports industrial applications such as welding, material handling, assembly, palletizing, and machine tending, including Motoman XRC‑based platforms where synchronized motion control is essential. Weighing approximately 10.3 kg and classified as a ~3 kW class device, it provides consistent power distribution and motion accuracy to maintain repeatable paths in high‑volume manufacturing. This is a discontinued/legacy unit with aftermarket availability; common replacements include Yaskawa SRDA series robot converters and SGDV/SGDA servo drives.
