Patent ID: 7035728

Claim:
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 selectively controlled switching means ( 27 , 28 , 29 ) for regulating the current flowing through said electroactuator ( 12 ); a control circuit ( 43 ) which is capable of driving the operation of each drive circuit ( 11 ) of said power circuit ( 42 ); a series of control modules ( 44 ), each of which controls said switching means ( 27 , 28 , 29 ) of an associated drive circuit ( 11 ), and comprises memory means ( 64 ) having at least two memory areas ( 64 a , 64 b ) each storing the same operating parameters for said drive circuits ( 11 ); reading means ( 62 ) for the operating parameters; and pointer means ( 71 ) which cooperate with said reading means and with writing means ( 80 ) for the operating parameters in order to define access of said writing means ( 80 ) to one of said memory areas ( 64 a , 64 b ) and simultaneously to define access of said reading means ( 62 ) to the other of said memory areas ( 64 a , 64 b ), and to swap the access rights of said writing means ( 80 ) and of said reading means ( 62 ) to said memory areas ( 64 a , 64 b ).
