Chapter 1 Introduction
The NI 7340 motion controller features motion profiles that are controlled with enhanced
PID / PIVff servo updates. Each axis 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 feedback rates. The NI 7340 motion controller also has
non-dedicated user I/O including 32 bits of digital I/O and four analog inputs for ±10 V signals,
joystick inputs, or monitoring of analog sensors. Additionally, the NI 7340 motion controller
analog inputs can provide feedback for loop closure.
RTSI
The NI 7340 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.
What You Need to Get Started
To set up and use the NI 7340 motion controller, you must have the following items:

NI PXI-7340 or PCI-7340 motion controller

NI-Motion 6.1 or later driver software and documentation

One of the following software packages and documentation:
– LabVIEW 6.0 or later
– LabWindows
™
/CVI
™
7.0 or later
– Measurement Studio
– C/C++
– Microsoft Visual Basic 6.0

A computer with an available PXI or PCI slot
Software Programming Choices
NI-Motion is a simple but powerful high-level application programming interface (API) that
makes programming the NI 7340 motion controller easy. All setup and motion control functions
are easily executed by calling into a dynamically-linked library (DLL). You can call these
libraries from C, Microsoft Visual Basic, and other high-level languages. Full function sets are
available for LabVIEW, LabWindows/CVI, and other industry-standard software programs.
