Working Principle:
The MM-PMC2-400 uses a dual-processor architecture: a high-speed DSP handles motion control at a fixed cycle (1 ms / 500 µs / 250 µs), while a separate RISC processor executes the PLC program and communication tasks. The motion engine computes trajectory setpoints for all 4 axes using real-time interpolation algorithms (linear, circular, 3D, polynomial). These setpoints are sent to servo drives via high-speed pulse outputs or analog commands. The look-ahead buffer (256 blocks) allows the controller to anticipate upcoming path changes, reducing following error and enabling smoother high-speed motion. The PLC processor and motion processor exchange data via dual-port RAM, ensuring tight synchronization between discrete logic and motion.
