The Compact Controller Board CCBu20 is an embedded all-in-one controller for piezo actuators. It features everything to drive and control a 2 axis piezo-mechanism in position loop. In standard, its integrated dual channel SG conditioner allows reading the position of the two axis of the mechanism. A powerful processor realizes closed-loop control at high refresh rate, and the controller can be tuned by the user with the HDPM45 interface. Thanks to a compact design, it has dimensions of only 91x77x37mm, making it suitable for embedded applications, or industrial applications where the volume is an issue. The Graphical User Interface to modify the parameters of the CCBu20 is similar to the UC digital controllers that can be downloaded on the dedicated page.
