The National Instruments PXI-7342 (Part Number: 779036-02) is a high-performance Stepper/Servo Motion Controller Module designed specifically for two-axis applications. This module features 32 digital I/O channels with a 12-bit input resolution and is equipped with dual processors for enhanced computational capabilities. The PXI-7342 supports multiaxis interpolation and operates on a real-time onboard operating system, allowing for complex motion control tasks including coordinated circular motion, gearing, point-to-point movements, and vector space motion, as well as blended trajectory control. It excels in executing advanced motion profiles, making it an ideal choice for machine builders and end-users who need quick and robust application development.
This controller is compatible with multiple operating systems, including Windows 2000, NT, XP, and provides real-time performance when used with LabVIEW. Software support is extensive, including tools such as NI Motion Assistant, Measurement Studio, LabWindows/CVI, and programming environments like Visual Basic and C/C++. Configuration of the hardware can be efficiently managed using the Measurement & Automation Explorer (MAX) tool. With a 62 ms PID loop update rate, the PXI-7342 also supports 3D contouring along with linear and circular interpolation, enhancing its application versatility.
Additionally, the controller module offers four general-purpose inputs for feedback in closed-loop control and simple monitoring. It features high-density 68-pin female VHDCI connectors for seamless external motion and digital I/O integration. Operating under various servo-control loop modes, including PID, PIVff, S-Curve, and dual loop, the PXI-7342 achieves a maximum pulse rate of 4 MHz and supports step output modes of step and direction or CW/CCW. Despite being designated as obsolete by National Instruments, the PXI-7342 remains available for purchase and repairs through Apex Waves. A three-year warranty is included, and comprehensive user and maintenance manuals can be downloaded for detailed guidance. For pricing inquiries, please contact a sales representative.
