  • Method and device for diagnosing a position encoder
    Patent number: 8428906
    Abstract: A method for determining a mixup in the terminals of a position encoder having a position encoder motor, which is bidirectionally drivable via a plurality of terminals, so that a mixup of at least two of the terminals of the position encoder motor leads to a reversal in the actuation direction of the position encoder, having the following steps of setting an actuating element of the position encoder to a zero setting, from which a motion of the actuating element is possible in one or two directions; driving the position encoder motor according to a diagnostic variable, which is selected so that, based on the actuation using the diagnostic variable, in the case of a non-mixup of the terminals and in the case of a mixup of the terminals, different absolute values of the changes are to be expected in the changes of the actuation position of the actuating element; recording a current change in the actuation position of the actuating element that comes about by the driving of the position encoder motor; establishi
