When we want to control a motion component (different types of motors) we need to use a device that will allow us to do so. This device will enable us to control to motion component easily, precisely and fast. The control devices can be motion controllers which command a motor or a feedback device that supply the controller with the required information for its operation. Medital offer several control architectures: Centralized, distributed or a combination of the two. Also, Medital offer several types of encoders: Rotary or linear, optical or magnetic, potentiometers and many more.
