Navigator-PC/104 Performance Motion Devices Motion Controller For Servo Or Step Motors

The Navigator-PC/104 Motion Controllers for servo or step motors are PC/104 cards that plug directly into a PC/104 connector. The Navigator-PC/104 boards are used in embedded control systems for industrial control, automation and robotic applications. They are available in 1, 2 and 4-axis configurations. The boards are designed for surface mount technology and use PMD's Navigator chipset, for either DC brushed, step or brushless DC motors (using external commutation). They are equipped with additional 256 KB memory to store extensive motion sequences and/or motion trace information to perform complex motion profiles without interrupting the host and to store motion trace information to gather comparison values for system performance checks, servo-tuning, maintenance and diagnostics.

With 124 to 168 commands, depending on model, the Navigator-PC/104 instruction set offers flexibility and versatility to software application programmers. Instructions are used to initialize and control the motion controller. User selectable profiling modes supported by the motion controller include S-curve, trapezoidal, velocity contouring and electronic gearing. The Navigator-PC/104 accepts input parameters such as position, velocity, acceleration and jerk from the host and generates a corresponding trajectory. The Navigator-PC/104 series compact design allows you to pay only for what you need and to be able to upgrade easily if necessary. Just stack additional cards to increase the number of axes.

The Navigator-PC/104 cards are extensively supported by state of the art software tools, resources and programs. Pro-Motion™ software, a Windows™ Graphical User Interface (GUI), provides a quick and convenient way to exercise the card. It allows system parameters, profile information and other useful motion information to be set and stored. In addition, Pro-Motion provides a powerful “motion oscilloscope” function that allows up to four real-time motion variables to be displayed at the same time, simplifying servo tuning and machine performance optimization. Complementing Pro-Motion is C-Motion, an Application Programmer’s Interface (API) comprised of a C-source code library for developing applications in DOS or Windows environments.
