National Instruments 7330 Series Stepper Motion Controllers
Features

• Linear Interpolation for Coordinating Multiple Axes
• Real-Time System Integration with Data Acquisition or Image Acquisition Boards
• High-Performance Stepper Generation for Ensuring Smooth Motion at High Velocities

The NI 7330 controller features advanced motion control with easy-to-use software tools and add-on motion VI libraries for use with LabVIEW. The 7330 controller is a stepper motor controller for PXI and PCI. The 7330 provides fully programmable motion control for up to four independent or coordinated axes of motion, with dedicated motion I/O for limit and home switches and additional I/O for general-purpose functions. You can use the 7330 motion controller for point-to-point and straight-line vector moves for stepper motor applications. The 7330 controller adds the ability to perform arbitrary and complex motion trajectories using stepper motors. Stepper axes can operate in open or closed-loop mode. In closed-loop mode, stepper axes use quadrature encoders or analog inputs for position and velocity feedback (closed-loop only), and provide step/direction or clockwise (CW) /counter-clockwise (CCW) digital command outputs. All stepper axes support full, half, and microstepping applications.

The 7330 uses an advanced dual-processor architecture that uses a 32-bit CPU, combined with a digital signal processor (DSP) and custom field programmable gate arrays (FPGAs), making the controller a high-performance device. The first-in, first-out (FIFO) bus interface and powerful function set provide high-speed communications while off-loading complex motion functions from the host PC for optimum command throughput and system performance.
