Motion Control Portfolio Delivers Flexibility, Scalability

March 31, 2021

PACMotion servo motion control portfolio offers an integrated automation solution for high-performance industrial applications. The portfolio includes a new motion controller that connects directly into the PACSystems RX3i programmable logic controller backplane for high-speed, high-precision performance with a synchronized motion for up to 40 coordinated axes, enabling end-users to scale up their motion systems without sacrificing performance.


The complete PACMotion portfolio includes a motion controller, servo motors, servo drives, and motion configuration software for applications in packaging, printing, material handling, semiconductors, food & beverage, and general manufacturing. The PACMotion PMM345 motion controller operates exclusively with PACSystems RX3i controllers, simplifying the architecture for seamless integration while enabling higher speeds and greater precision.


Emerson’s patented technology enables precise, jerk-free positioning, preventing material slippage and production losses and improving machine efficiency. On-the-fly electronic reconfiguration allows users to implement rapid changeovers without stopping production to deliver shorter production runs and increased machine utilization.

  • Built on open EtherCAT communications
  • Compatible with all PACSystems RX3i backplane CPUs
  • Consistent motion update rate regardless of the number of axes
  • Expandable design with up to 50 coordinated axes of control in a single system: 40 physical and 10 virtual
  • Available Fiber Terminal Block (FTB) allows distributed motion-centric I/O for simple wiring
  • Capable of changing motion profiles on the fly
  • Same footprint as PMM335 predecessor for easy migration
  • Integrated with PAC Machine Edition Software for consistent programming
  • Double precision (64-bit) floating point
  • Entire system is synchronized to ensure all components work together
