EASY-TO-CONFIGURE CONTROLLER CAN CONTROL UP TO 128 AXES SIMULTANEOUSLY

Delta Tau Data Systems, Inc. offers its Power PMAC Controller. With its ability to control up to 128 axes simultaneously, the Power PMAC is an easy-to-configure controller, whether for basic or sophisticated tasks. Thanks to a new generation of embedded Power PC microprocessors, the Power PMAC has superior computational capabilities together with a high level of peripheral integration.

The Power PMAC employs a full Linux operating system with a hard-real-time kernel, creating a complete general-purpose computing environment. But it also comes embedded with a complete motion and machine control software environment that builds on the success of Delta Tau´s existing PMAC and Turbo PMAC controllers. This results in a powerful solution for almost any commercial, industrial, or military motion control application. It rescues machine control designers from a classic dilemma: the choice between a dedicated controller that makes executing basic tasks easy but can limit the sophistication of what can be accomplished; or a general-purpose computing engine that permits the use of the full sophistication of modern programming languages that make it very difficult just to get from Point A to Point B.

In virtually all aspects of the machine control, users have the choice between using the built-in algorithm and providing their own software, written in C or C++ and compiled with the public-domain GNU compiler. C programs can be written manually or generated from environments such as IEC-1131 or Matlab/SimulinkTM, as well as EPICS or other task-oriented programs. The Power PMAC´s built-in script language for both motion sequences and general machine and I/O logic, automatically takes care of many issues that a standard language such as C does not: proper timing and pipelining of move sequences, simple or complex, automatic type matching of different variables (short-word and long-word, fixed-point and floating-point). It also provides the advanced tools of a good integrated development environment (IDE) – editors, debuggers, project managers – that standard programming languages have. It also retains the ability to issue simple on-line commands directly, permitting the user to converse easily with the controller.

The Power PMAC supports the new 3rd-generation machine-interface ASIC, which has unprecedented speed, integration, and feature set. The ASIC supports quadrature encoders with hardware 1/T interpolation, as well as sinusoidal encoders and resolvers with hardware arctangent interpolation, and most of the common serial encoder protocols such as EnDat2.2TM and SSI, plus analog, PWM, and pulse-and-direction outputs.
