Installation

Brushless DC cards provide multi-phase motor command signals, using Hall-based or sinusoidal

commutation located on the Navigator-PC/104 card. These cards are intended to interface with brushless DC

amplifiers and motors, although they can also control other 3-phase devices such as AC Induction motors.

Pulse & direction cards output standard pulse & direction signals, and are intended to interface with

amplifiers which accept that command format.

Microstepping cards output multi-phase analog (+/- 10V) or PWM (pulse width modulation)

waveforms. They are designed to control 2 or 3-phase step motors using amplifiers that accept this

command format.

Mixed motor cards provide the ability to control DC-brush, brushless DC or microstepping motors within

the same card. The output formats are software programmable, allowing various combinations of

motor types and axis number to be configured.

For complete information on motor output formats and other information see the Navigator Motion

Processor User’s Guide.

1.1 Software

Two major software packages are provided with the Navigator-PC/104 cards: Pro-Motion, an interac-

tive Windows-based exerciser program and C-Motion, a C-language library which simplifies the

development of motion applications for Navigator-PC/104 cards.

Pro-Motion is a sophisticated, easy to use exerciser program that allows you to set and view all card

parameters, and exercise all card features. Pro-Motion features include:

„ Motion oscilloscope graphically displays processor parameters in real-time

„ Interactive servo tuning

„ Project window for accessing card parameters

„ Ability to save and load current settings

„ Distance and time units conversion

„ Motor-specific parameter setup

„ Axis shuttle performs continuous back and forth motion between two positions

„ Command window for direct text command entry. It also serves as a communications

monitor that echoes all commands sent by Pro-Motion to the card.

C-Motion provides a convenient set of callable routines that comprise all of the code required for

controlling your Navigator-PC/104 card. C-Motion includes the following features:

„ Axis virtualization

„ The ability to communicate to multiple Navigator-PC/104 cards

„ The ability to link easily to any “C/C++” application

Pro-Motion is described in section 3, Using Pro-Motion, page 35, C-Motion is described in detail in section

4, Developing Your Own Applications with C-Motion, page 51.
