IRVINE, Calif., Nov. 23, 2010 — Newport Corp. has introduced the newest member of its Conex integrated stage and controller product series. The compact Conex-AGP controller is preconfigured with an Agilis AG-LS25-27P linear stage that includes a miniature, built-in, direct-read linear encoder. The linear stage, which integrates both products, offers quick set up and control with closed-loop positioning performance at an affordable price.
The system combines an advanced piezo motor linear stage with the low-cost architecture of the Conex controller family. The ultracompact controller delivers submicron, bi-directional repeatability of 0.3 µm, making it suitable for applications in confined spaces that require integrated, single-axis control. The linear stage is compact, offers 27-mm travel and 0.2-µm metal-insulator-metal.
The Conex-AGP closed-loop algorithm is a simplified version of the typical DC servo loop algorithm, and combined with the stage’s linear encoder, provides a highly repeatable bi-directional system that meets the need for motion control of repetitive tasks.
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 a simple and intuitive graphical user interface, accessible via USB. For added convenience, the USB interface also supplies power to the controller, eliminating the need for additional power supplies and/or cables.
