Charlottesville, VA –  PACMotion is a from GE Fanuc Intelligent Platforms, a unit of GE Enterprise Solutions. It is designed to serve the high-end needs of complex motion applications andously control of up to 40 axes. Paired with Fanuc servos, it provides an unmatched solution for machine automation, the company says.

PACMotion is a motion controller from GE Fanuc Intelligent Platforms.

“PACMotion provides a striking leap in performance,” says Paul Derstine, motion product manager for GE Fanuc Intelligent Platforms . “PACMotion delivers the ultimate in scalable motion control combining a distributed CPU architecture integrated across a high speed backplane.”

GE Fanuc says using the

Less variablity
Variability in manufacturing is the enemy of quality and yield. In complex machining operations where many axes need to be synchronized, motion controllers that have one microprocessor for all functions will see loop update performance degrade as the CPU processes more information for more axes, company says. Longer loop update times can introduce errors and variability in high-speed manufacturing; PACMotion eliminates this variability with PACcore architecture.

Derstine says this “is the motion controller of choice for OEMs that need an integrated motion and machine logic solution. The proven dependability of GE Fanuc products allows them to deliver unprecedented productivity in their machines through increased efficiency, flexibility, and reliability enabled by unique features such the PACcore multi-processor architecture and simultaneous updating of synchronized axes with no performance degradation.”

“Motion path planning is an incredibly intensive computational process,” says Michael Harsh, chief technology officer for GE Enterprise Solutions. “Our hybrid distributed architecture makes it possible to add axes but not increase the load on the central processor, thereby keeping the performance exactly the same regardless of the number of axes in a system. For complex motion applications, this is critical.”

Shared resources
PACMotion simplifies programming by sharing a common database, eliminating complex data exchange between different programs, and reduces the learning curve required with two programming languages, therefore boosting engineering productivity, and easing system integration challenges, company says.

According to Himanshu Shah, ARC Advisory Group , “End users and OEMs are continually seeking higher performance from production machinery. PacMotion is designed to bring out that extra performance from the same machine. In fact, it could help provide manufacturers with an edge over their competition in many multi-axis machine applications due to embedded advanced features such as scalability without degrading performance, seamless blending of jerk limited moves anywhere along the motion profile, and powerful diagnostic tools for maximum machine availability. PACMotion should expand GE Fanuc’s opportunities in the machine control market.”

Craig Resnick, ARC Advisory Group, adds that the technology “demonstrates the continued evolution of PAC platforms such as the RX3i to better address the integration issues confronting manufacturers, machine builders and OEMs by further extending the multi-disciplined domain expertise of automation systems. Machine builders and OEMs want fewer components and seek platforms that enable multiple-discipline development and functionality without compromising the technical integrity of their solution. PAC platforms today are proving that multi-disciplined solutions and best-of-breed solutions are not mutually exclusive, which results in an increased return on assets, reduced lifecycle costs, and a lower total cost of ownership for manufacturers, machine builders and OEMs.”

The new motion controller serves the needs of high-speed machines with a high number of synchronized axes. Industries needing this feature would include packaging, assembly, woodworking, metalworking, and printing. GE Fanuc Intelligent Platforms, a joint venture between General Electric and Fanuc Ltd of Japan, is a high-performance technology company and a global provider of hardware, software, services, expertise and experience in automation and embedded computing, serving "virtually every industry," company says.
