ABSTRACT:
A method for controlling the axes of motors, for machine tools and the like, including the steps of: calculating, from a sequence of relative position data of each axis and of actuation states at each definite instant, a path for each individual axis, starting from parameters of initial speed, number of steps and final speed; defining a three-dimensional matrix that contains, for each axis, initial speed, number of steps and final speed, each element of the three-dimensional table, constituted by the intersection in space of the three parameters, containing an address that is suitable to point to the vector which describes a corresponding waveform; driving the axis according to the waveform.
