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.
NI Motion Assistant offers a point-and-click interface for creating motion
control sequences quickly and easily. When you have created a motion
task, you can use NI Motion Assistant to generate the task in LabVIEW
or C code or code recipes to speed up development.
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.
The PCI-7390 also offers high-performance encoder features such
as position capture triggers and position compare breakpoints for highspeed 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.

Software
The 100-pin SCSI I/O connector provides all the signals for four axes
of closed-loop motion control, including encoder feedback, limit and home
inputs, breakpoint (position compare) outputs, trigger (position capture)
inputs, inhibit (alarm) inputs, and in-position inputs. The connector also
can provide shutdown (emergency stop) input, drive (servo) ready inputs,
inhibit (drive enable) outputs, alarm clear outputs, and general-purpose
inputs and outputs. All inputs and outputs are optically isolated.
The PCI-7390 incorporates the NI RTSI bus, which provides high-speed
connectivity among National Instruments products, including image
acquisition and data acquisition products. Using the RTSI bus, you can
easily synchronize several functions to a common trigger or timing event
across multiple motion, image, or data acquisition devices.
