Abstract
A drive device for inductive electroactuators equipped with a power circuit comprising a drive circuit for each electroactuator; each drive circuit comprising a series of selectively controlled transistors for regulating the current flowing through the electroactuator; a control circuit which is capable of driving the operation of each control circuit and a series of control modules, each of which controls the transistors of an associated control circuit; and a memory having at least two memory areas each storing the same operating parameters for the drive circuits; an internal microcontroller for reading the operating parameters; and a series of pointer registers which cooperate with the internal microcontroller and with an external microcontroller to define access of the external microcontroller to one of the memory areas and simultaneously to define access of the internal microcontroller to the other memory area, and to swap the access rights of the internal microcontroller and of the external microcontroller to the two memory areas.
