Drive device for inductive electroactuators

A drive device (41) for inductive electroactuators equipped with a power circuit (42) comprising a drive circuit (11) for each electroactuator (12); each drive circuit (11) comprising a series of selectively controlled transistors (27, 28, 29) for regulating the current flowing through the electroactuator (12); the drive device (41) moreover comprising a control circuit (43) which is capable of driving the operation of each control circuit (11) and comprises a series of control modules (44), each of which controls the transistors (27, 28, 29) of an associated control circuit (11); and a memory (64) having at least two memory areas (64a, 64b) each storing the same operating parameters for the drive circuits (11); an internal microcontroller (62) for reading (44b) the operating parameters; and a series of pointer registers (71) which cooperate with the internal microcontroller (62) and with an external microcontroller (80) in order to define access of the external microcontroller (80) to one of the memory areas (64a, 64b) and simultaneously to define access of the internal microcontroller (62) to the other memory area (64a, 64b), and to swap the access rights of the internal microcontroller (62) and of the external microcontroller (80) to said two memory areas (64a, 64b).
