Overview

The NI PCI-7390 is a position (pulse) command stepper motion controller

with isolation designed for use with drives that accept position (p-)

command mode or step (pulse) command input. The PCI-7390 has

accessories specifically designed for direct connectivity to Yaskawa

Sigma II, Mitsubishi MR-J2S, and Panasonic Minas A drives. The

PCI-7390 provides fully programmable motion control for up to four

independent or coordinated axes of motion. It features dedicated motion

I/O for limit and home switches and additional I/O for general-purpose

functions such as in-position, inhibit input/drive alarm, and servo ready.

You can use the PCI-7390 controller for point-to-point and straight-line

vector moves. The PCI-7390 also performs arbitrary and complex motion

trajectories through circular, spherical, or helical interpolation. The

PCI-7390 uses quadrature encoders for position and velocity feedback

(closed-loop only) and provides advanced encoder functions such as trigger

(position capture) inputs and breakpoint (position compare) outputs.

Software

The PCI-7390 is shipped with the NI-Motion driver, which includes a VI

library for NI LabVIEW software and functions for NI LabWindows/CVI,

C, and Visual Basic. For other languages, you can execute all setup and

motion control functions by calling into a dynamic link library (DLL). The

NI-Motion VI library implements the full API, along with a useful set

of example programs. The NI-Motion software also includes a series

of example programs for use with ANSI C-based LabWindows/CVI.

Hardware

The PCI-7390 is a high-performance controller that uses an advanced

dual-processor architecture including a 32-bit CPU combined with a

digital signal processor (DSP) and a custom field-programmable gate

array (FPGA). The PCI-7390 uses the DSP for all closed-loop control and

motion trajectory generation. The DSP chip is complemented by a

custom FPGA that performs the high-speed encoder interfacing, position

capture (trigger) input and position compare (breakpoint) output functions,

motion I/O processing, and pulse generation for hard real-time

functionality. The embedded CPU runs a multitasking, real-time OS

and handles host communications, command processing, multiaxis

interpolation, error handling, general-purpose digital I/O, and overall

motion system integration functions.

as position capture triggers and position compare breakpoints for high-

speed synchronization of motion with actuators, sensors, and other parts

of the complete motion system. You can program a position compare output

to transition when the associated encoder value equals the breakpoint

position. You can use a breakpoint output to directly control actuators or

as a trigger to synchronize data acquisition or other functions in the

motion control system.

The PCI-7390 also offers high-performance encoder features such
