Coordinated Control

Aerotech’s control technologies can coordinate and synchronize up to 32 axes of motion of any motion technology to sub-microsecond servo-loop synchronization and sub-millisecond path trajectories. This tight synchronization between all motion axes results in higher precision processing and faster process throughput. Examples of Aerotech controller features that enable coordination and synchronization are:

EasyTune Advanced Motion Controller Autotuning Tool

EasyTune® is the most advanced autotuning tool available in a commercial motion controller. Entirely data-driven, the algorithm mimics the process followed by an experienced controls engineer. Many existing tuning techniques rely on basic model-fitting or “rules-of-thumb” that ignore machine resonances or nonlinear behavior, but EasyTune directly measures and compensates for those effects. It assumes no…
