Abstract: An electronic control by frequency inverter of the displacement system of an irrigation or fertirrigation set is made up of structured pipelines, in which the water distribution sprayers are mounted, and which are coupled to each other, and supported by movable towers which are moved by gear motors driving by means of cardans the wheel gear that in turn drive pneumatic wheels, moving the structure about a fixed point, or pivot point, which is the central tower. The driving of the gear motors of each tower is performed by an electric control unit via a frequency inverter, with analogic signal, preferably a potentiometer, or position encoder digital sensor or optical sensor of alignment with relation to the front and back tower.
