Claim 1:
2. The method as claimed in claim 1, further comprising:
the first sensor element has electronic devices for outputting a signal SR proportional to the number of belt revolutions;
the rotor position of the drive motor is determined by the second sensor element and is output as a signal SM proportional thereto;
the initial relationship between a specified number NR of belt revolutions and the rotor position determined for this, which is present when the belt drive is new, is calculated in the computing unit and is stored as a reference value; and
wherein the associated rotor positions are then repeatedly determined for further belt revolutions corresponding to the specified number NR and their current relationship is compared with the reference value, wherein a warning or alarm signal is output by the computing device after a specified tolerance value between the current relationship and the reference value has been exceeded.
