Piezo Motor Linear Stage With Closed-Loop Controller and Driver
The CONEX-AG-LS25-27P is the first of two specialized stage products to be released that combines an advanced piezo motor linear stage with the low-cost architecture of the CONEX controller family. The ultra-compact controller delivers sub-micron, bi-directional repeatability of 0.3 µm, making it ideal for applications in confined spaces that require integrated, single-axis control. The linear stage is also very compact, capable of 27 mm travel and 0.2 µm metal-insulator-metal (MIM).
The controller’s versatile deadband function allows the user to modify the closed-loop parameters to program the acceptable deviation from a position, and to hold that position steady. The new controller features the simple and intuitive CONEX GUI, accessible via USB. For added convenience, the USB interface also supplies power to the controller which eliminates the need for additional power supplies and/or cables.
