Providing 50,000 pulses per revolution, the H infinity control feature of Reliance's new servo system accommodates a wide range of load variation during motion. H infinity control responds to dynamic loads across the entire speed range, reducing the need to tune gains, allowing higher inertia mismatches and providing increased motion flexibility. In addition, unlike microstepping devices, the vector drive coupled with the 50,000 count encoder gives smooth, efficient motion at low speeds.
