Claim 9:
10. The method according to claim 1, wherein detecting the current value at the point (W) at which the armature disk begins to move includes:
calculating a further state variable from the measured state variables current (I) and voltage (U) and from a resistance value of the coil (Rs) or from a variable derived from the measured state variables current (I) and voltage (U) and from the resistance value of the coil (Rs);
(ii) comparing the further state variable with a predefined value of this further state variable stored in the monitoring module for movement of the armature disk in the spring-loaded brake; and
(iii) determining and outputting the current value at the point (W) at which the movement of the armature disk begins,
characterized in that the variable derived from the measured state variables current (I) and voltage (U) is the filter function of the measured state variable current (I) and voltage (U).
