Abstract (en)

[origin: WO2009147013A2] The invention relates to a method for controlling a motor (2), especially for opening and closing a door, wherein the motor (2) is controlled by means of a pulse width-modulated switching signal (PWM) that is divided into a specifiable number of pulse width-modulated control signals (PWM1, PWM2) for actuating a bridge circuit (4) to a corresponding number of functional channels (F1, F2). According to the invention, the functional channels (F1, F2) are switched off independently from each other by means of at least one or more switch-off signals (AS1, AS2) on at least one switching circuit of a number of independent switching circuits (26.1, 26.2) corresponding to the number of functional channels (F1, F2).
