Introduction
This chapter includes information about the features of the National
Instruments PXI/PCI-7350 controller and information about operating the
device.

About the NI 7350 Controller

The NI 7350 controller features advanced motion control with easy-to-use
software tools and add-on motion VI libraries for use with LabVIEW.

Features

The NI 7350 controller is a combination servo and stepper motor controller
for PXI, CompactPCI, and PCI bus computers. It provides
fully-programmable motion control for up to eight independent axes of
motion. Coordinated motion is supported through multi-dimensional
coordinate spaces. Each axis provides dedicated motion I/O for limit and
home switches and additional I/O for general-purpose functions.
You can use the NI 7350 controller for point-to-point andstraight-line
vector moves. The NI 7350 also performs arbitrary and complex motion
trajectories through circular interpolation and contouring.
Servo axes can control DC brushed or brushless servo motors, servo
hydraulics, servo valves, and other servo devices, such as closed-loop piezo
motor systems. Servo axes always operate in closed-loop mode. These axes
use quadrature encoders or analog inputs for position and velocity feedback
and provide analog command outputs with an industry-standard range
of±1 0 V.
Stepper axes control stepper motors in either open or closed-loop
mode. They use quadrature encoders or analog inputs for position
feedback (closed-loop only), and provide step/direction or clockwise
(CW)/counterclockwise (CCW) digital command outputs. All stepper axes
support full, half, and microstepping applications.
