PACMotion maximizes the potential of your machine so that you can sell more. When you have high performance needs that include high-speed motion applications, PACMotion provides the performance, flexibility, and productivity to make the most for your customers. PACMotion is a revolutionary new motion controller for the PACSystems RX3i, breaking the mold of what a motion controller can do. It controls up to 40 axes in a single rack over a high-speed backplane, with a hybrid distributed control architecture to ensure you get the speed and accuracy to maximize your machine.
Productivity
- PACMotion updates the position loop and path planning at consistent rates regardless of the number of axes
- No performance degradation as you increase the number of axes
- Path planning and all servo loop closure is done on a powerful coprocessor in each PACMotion module to maximize processor time available to run your application program
- Motion path planning updated at a blazing 1 millisecond
- Position loop update occurs every 500 microseconds
- Axes are updated simultaneously to eliminate phase delays that can cause positional errors
- Distributed control architecture keeps the processing load off of the main processor so to ensure consistent performance at high speeds and high axis counts
- Noise immune fiber optic I/O and servo interface increases system reliability maximizing machine availability
- Three high speed interrupts for each PACMotion module can be configured as event or time-based interrupts to the RX3i CPU enabling tight coordination of motion and machine events
- On demand data exchange between PACMotion modules and RX3i CPU minimizes scan impact and ensures program access to the most recent data
- Up to eight axes can be configured for synchronous or time-delayed start; start signal is independent of RX3i CPU eliminating potential processing delays
Flexibility
- Flexible configuration of the master axis, I/O, and system architecture
- Centralized or hybrid distributed control
- Amplifiers can be located centrally or up to 400 meters from the rack
- On the fly changes make it easy to do instant product change-over at the push of a button for short production runs
- A flexible master position source can be a real (encoder) or a virtual (time-based) master and master sources can be changed on the fly
- Master axis commands are passed over the high speed backplane -- any axis to be a master or a slave to any other axis
- Engineering Productivity for Quicker Time to Market
- Integrating the motion and logic onto one system reduces program complexity and greatly simplifies the synchronization of motion and machine control logic
- A common programming language, tag database, and function blocks allows faster program development time to market and machine commissioning
- More than 50 built-in motion functions designed to comply with PLCOpen standards are available in Function Blocks or Structured Text languages
- Powerful diagnostic tools enable high speed data capture and graphical display and a separate diagnostic program that runs independent of the main program
