Precision Motion Control
Motion control often involves twin demands of increasing speed and precision. As speed impacts productivity, it is an area of much interest. Improvement of the machine efficiency generates immeasurable added value, including reduction of labour and the machine floor area for the same quantity of production. But, when machine speed increases, a problem with the stop precision is often generated. In order to resolve this challenge, diversified grades of position controllers have been developed and used. It is easy to visualize through the difference of accuracy offered by positioning using Induction motor with limit switch controlled and same as using AC drives with highly sophisticated Motion Controllers.
In modern machines, AC servo systems with features like synchronization with multiple moving axes – rotary or linear, electronic CAM and on the fly CAM generation, deliver low footprint compared to delivery capacity, maximum positioning accuracy like 10-4 degree of rotation, advanced control methodology like auto-tuning, vibration adaptive filters etc. They are the emerging actuation systems for optimum productivity for today’s manufacturing.
