LabVIEW for Windows Motion Control VIs Now Available for Programming PC AT
Bus Stepper Motor Board

September 9, 1992 - Austin, TX - National Instruments, (Austin, TX) and
nuLogic, Inc., (Needham, MA), a member of the National Instruments
Alliance Program, announced today a new add-on motion control library for
use with the new LabVIEW for Windows. The Motion Control Virtual
Instruments (VI) package is used for programming the pcStep 3-Axis Stepper
Motor Control board. Since early 1990, nuLogic has offered motion control
VI libraries for LabVIEW for Macintosh, which are used for controlling
nuStep stepper and nuControl servo control boards. These products are used
in motion control applications in areas such as machine vision, medical
microscopy, laboratory automation, machine tool production automation, and
test systems.

The Motion Control VIs for LabVIEW for Windows include all control and
status commands for programming the pcStep 3-Axis Stepper Motor Control
board. The VIs have fully integrated realtime capabilities for motion
control within the LabVIEW environment. With the Motion Control VIs, users
can apply the simplicity and power of the LabVIEW graphical programming
environment to motion control applications. Users can also examine the
block diagrams of the Multi-Axis Setup and Initialization VIs from within
LabVIEW. The VIs also include a number of example programs such as an X-Y
positioning application and open and closed-loop stepper motor control
panels.

The Motion Control Virtual Instruments include VIs for start/stop commands,
position, velocity, acceleration, trajectory control, multi-axis setup and
initialization, I/O ports and limit-switch commands, and low
level-hardware interfaces for communicating with the pcStep board.

"Design engineers using LabVIEW for Windows, the Motion Control VIs, and
pcStep can now more effectively use their time-solving
application-oriented problems rather than programming," said John Miller,
Director of Sales and Marketing for nuLogic. "In the past, some of these
engineers had to become full-time programmers and part-time machine
designers. By programming graphically with LabVIEW, they can devote most
of their time to machine design instead of worrying about the tedious
programming details."

Availability and For More Information 

The Motion Control Virtual Instruments package is available now from
nuLogic for $395. The VIs work with the pcStep 3-Axis Stepper Motor
Control board, which is also available now from nuLogic for $1,095 ($1,395
closed loop). For more information about the Motion Control Virtual
Instruments or pcStep control board, please contact nuLogic, Inc., 475
