Card điều khiển chuyển động NI PCI-7330

Features
The NI 7330 motion controller is a stepper motor controller for PXI and PCI. The NI 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 NI 7330 motion controller for point-to-point and straight-line vector moves for stepper motor applications. The NI 7330 motion 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.
Hardware
The NI 7330 is a high performance motion controller that uses an advanced dual-processor architecture including a 32-bit CPU, combined with a digital signal processor (DSP) and custom field programmable gate arrays (FPGAs). The first-in, first-out (FIFO) bus interface and powerful function set provide high-speed communications while offloading complex motion functions from the host PC for optimum command throughput and system performance. Each axis of the NI 7330 motion controller has motion I/O for end-of-travel limit and home switch inputs, breakpoint output, trigger input, and encoder feedback. Refer to Appendix A, Specifications, for information about the encoder feedback rates. The NI 7330 motion controller also has non-dedicated user I/O including 32 bits of digital I/O and four analog inputs for ±10 Vsignals, joystick inputs, or monitoring of analog sensors. Additionally, the NI 7330 motion controller analog inputs can provide feedback for loop closure.
RTSI
The NI 7330 motion controller supports the National Instruments Real-Time System Integration (RTSI) bus. The RTSI bus provides high-speed connectivity between National Instruments products, including image acquisition (IMAQ) and data acquisition (DAQ) products. Using the
RTSI bus, you can easily synchronize several functions to a common trigger or timing event across multiple motion, IMAQ, or DAQ devices
