MACRO

Monday, November 22nd, 2010

MACRO is an acronym for Motion and Control Ring Optical and is a non-proprietary digital interface developed by Delta Tau for a single wire connection between the multi-axis motion controllers, amplifiers, and I/O through a fiber optic or twisted pair copper (RJ45 connector) ring. MACRO minimizes wiring complexity, reduces hardware and eliminates noise in large systems. The high-speed 125 Mbits/sec transfer rate is capable of closing the servo loops across the MACRO ring, allowing the flexibility to choose distributed intelligence or centralized control.

Turbo PMAC2 Ethernet Ultralite

The Turbo PMAC2 Ethernet Ultralite is a new MACRO ring controller capable of handling 32-axis of control in a convenient, stand-alone package. Communicating to the PC via Ethernet /USB/Serial, the controller provides simplified wiring to the UMAC MACRO, Geo MACRO Drives, MACRO peripherals and any other third party MACRO devices.

The Delta Tau Turbo PMAC2 Ethernet Ultralite high-speed 125 Mbits/sec transfer rate is capable of closing the current loop and servo loop across the MACRO ring, allowing the flexibility to choose distributed intelligence or centralized control through a fiber optic or twisted pair copper (RJ45 connector) ring.

Macro Board Level

Available in a PCI or VME bus format, the MACRO interface board level controllers can control up to 32 axes of distributed or centralized machine control over a fiber optic link. Referred to as the Turbo PMAC2 Ultralite boards, working in combination with the UMAC MACRO, Geo MACRO Drives, MACRO peripherals or any other MACRO interface device which can be separated by great distances from the host computer.

UMAC MACRO

By simply changing the CPU card in a UMAC Turbo system to a MACRO CPU, you can change the personality of UMAC system to a UMAC MACRO station. Working with a Turbo PMAC2 Ultralite or another UMAC Turbo with MACRO Interface, the UMAC MACRO station can be distributed to a local area on the MACRO ring while retaining all the functionality of a UMAC Turbo.

Geo MACRO Drive

The Geo MACRO Drive interfaces to the controller through the fiber-optic MACRO 125 Mbit/sec ring or RJ45 (default), accepting numerical command values and returning numerical feedback values over the ring. Normal ring operation allows a choice of sending PWM commands, torque commands, velocity commands or position commands. The Geo MACRO Drive accepts many types of motor position feedback for loop control and feedback to the master controller. I/O can be transmitted on the ring for high level integration such as limits, home flag and general-purpose I/O points. Typically, the Geo MACRO Drives are commanded by either a Turbo PMAC2 Ultralite board, UMAC or QMAC System, providing a convenient solution for distributed or centralized control using a fiber optics connection or RJ45.

MACRO Peripherals

The MACRO Peripherals are a series of accessories that have a MACRO interface which allows you to distribute specific capabilities to a local area on the MACRO ring. Features include: analog and digital I/O, A/B Quad and Sinusoidal encoder feedback, x4096 interpolation, Analog, PWM and Stepper axis interface, DeviceNet, Profibus and CanOpen fieldbus interfaces, and many more features to come.

Delta Tau Power PMAC – No Compromises Needed

Thursday, October 8th, 2009

The Power PMAC is a full-fledged general-purpose computing engine with a true real-time multi-tasking operating system. Yet, it comes embedded with Delta Tau’s latest motion and machine-control programming environment, built on over 25 years of experience in producing state-of-the-art controllers that are easy to use.

This gives machine control designers the best of both worlds. In virtually all aspects of the machine control, users have the choice between using the built-in motion and PLC algorithms or providing their own software written in C or C++ and compiled with the GNU compiler under the terms of GPL.

The Power PMAC uses the latest generation of embedded Power PC processors. As embedded processors, most require no active cooling, improvement cost, size, and reliability. Still, these processors are lightning-fast, with hardware implementation of 64-bit floating-point mathematics. This automatically provides the required resolution and range for virtually any motion-control application imaginable, without hurting computational efficiency.

The processors can support gigabytes of solid-state memory, both active and non-volatile. The base configuration provides 512 MB/1 Gig/2 Gig of DDR active memory, with error correction; 512 MB of user flash memory; USB memory sticks and NAND-flash “camera cards” can be used as well. Even applications that require multiple days to execute a motion sequence can now be accomplished without real-time streaming of the data.

Efficient 100-Base-T or 1000 Base-T Ethernet along with USB2 interfaces are built directly into the processors permitting data transfer rates close to the theoretical maximum bit rates. This eliminates the need for an awkward backplane-bus (e.g., PCI) interface in virtually all applications, even those requiring the streaming of thousands of motion blocks per second.

Want the controller to execute a complex “G-code” motion sequence generated by an industry-standard CAD/CAM program? Just download the program file to the Power PMAC and let the built-in interpreter and automatic motion sequencer take over.

Want to use object-oriented C++ code to govern the overall machine “PLC” logic on the same machine? Write the code in industry-standard language in a sophisticated integrated development environment (IDE), cross-compile it with the public-domain GNU compiler, and download it to the Power PMAC. Alternatively, create the logic graphically in one of the resident IEC-11631 standard forms that automatically generates C code, then run the resulting code. Do the same with programs such as “EPICS” that can simply be loaded into and executed in the CPU.

Happy with the built-in servo algorithms? Just set a few gain terms with the sophisticated automatic or interactive tuning utilities. Have a special servo algorithm you need implemented? Either write it directly in C or use a tool like Matlab’s Simulink and Real Time Workshop to generate the C code, cross-compile it and download it to the Power PMAC.
