Patent ID: 7038412

Claim:
An arrangement comprising an electric motor ( 10 ; 10 ′), and a microprocessor ( 12 ), for influencing at least one motor function, having a terminal (A, A′), wherein an output level on said terminal (A, A′) of the microprocessor ( 12 ) is switchable by program-controlled switching operations within said microprocessor between a high level and a low level; and further comprising a first voltage divider ( 20 , 22 ) having two terminals connected, in operation, to two different predefined potentials and having a tapping point ( 18 ) thereof connected to said microprocessor terminal (A, A′) via a resistor ( 17 ), in order to make the potential at that voltage divider tapping point ( 18 ) switchable between at least two values by program-controlled switching of said level on said terminal, and by switching said potential at said tapping point, to influence a parameter of the motor ( 10 ; 10 ′).
