Product Description
The Navigator®-ISA Motion Controllers for servo or step motors are PC-based ISA-Bus cards that fit directly into an IBM-compatible slot. The Navigator-ISA 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 completely designed in 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 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 118 to 168 commands, depending on model, the Navigator-ISA 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 processor include S-curve, trapezoidal, velocity contouring and electronic gearing. The Navigator-ISA accepts input parameters such as position, velocity, acceleration and jerk from the host and generates a corresponding trajectory on-the-fly. Onboard memory is available for downloading complex multi-dimensional motion profiles and tracing profile data.
The Navigator-ISA 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.
