Industrial Applications

1. High-speed robotic packaging cell control

The 0.5 ms task cycle, 32-axis synchronization, and support for up to 8 robots make it suitable for coordinated pick-and-place and packing lines.

Problem Solved

Coordinates multiple robots and servo axes with deterministic timing to prevent throughput loss and motion desynchronization.

2. Multi-station assembly machine control

The controller can manage sequence logic plus synchronized motion for complex assembly machines with multiple coordinated stations.

Problem Solved

Replaces fragmented PLC and motion controller architectures with one unit that handles sequencing and motion together.
