Method to command and control an electric motor of an automation unit. The unit comprises a mechanical member, driven by a drive shaft, a central command and control unit, and a position detection mean. The method provides that the central command and control unit receives the position signals of the shaft of the electric motor and/or of the mechanical member from the position detection mean, divides the operating cycle into a plurality of sub-phases equal with respect to each other, consisting of elementary units and, for each of said sub-phases, or multiple of sub-phases, selects predefined or self-learnt current reference values, and generates a signal consisting of an instantaneous current reference (feed forward) for the electric motor.

Method to command and control the electric motor of an automation unit and connected system

Method to control the interference and/or collision between mechanical members of at least two operating or one operating unit with respect to fixed positions. At least one operating unit is associated with a position detector or with a position simulator, and is equipped with an electric which drives a mechanical member. The method is managed by a management and control unit. The control of the operating units occurs in two phases, verifying point-by-point the position of the mechanical member as a function of the current dynamics and the braking or acceleration times and spaces (first phase), and verifying the intensity of point-by-point current supplied to at least one electric motor (second phase).
