Motion Controller controls up to 128 axes simultaneously.
September 29, 2008 -
Employing Linux OS with hard-real-time kernel, Power PMAC comes embedded with complete motion and machine control software. Unit features 800 MHz and 1 GHz RISC processors with hardware floating-point engine, permitting programmed move block rates up to 5,000/sec with controlled acceleration and jerk. Device includes 100Base-T and 1000Base-T Ethernet TCP/IP communications with DMA streaming, plus web server that supports direct browser access for development, maintenance, and HMI.

Power PMAC, The Motion Computer that Provides the A to Z for Going From A to B
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/Simulink(TM), 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.
Some of Power PMAC´s outstanding features include:
o 800 MHz and 1GHz RISC processors with hardware floating-point engine, permitting programmed move block rates of up to 5000 per second with controlled acceleration and jerk
o 100-Base-T and 1000-Base T Ethernet TCP/IP communications with highly efficient DMA streaming
o PCI Express, USB, SATA, and RS-232 interfaces to support keyboard, video, disk drive, and other interfaces, making the PPMAC a complete, stand-alone RT Linux-based PC which is basically part of the system.
o Built-in web server to support direct browser access for development, maintenance, and HMI
