bus system b which connects all the assemblies of course a uniform bus system is not absolutely necessary for the provision of adjustment data items it is also conceivable for a plurality of data line systems which are parallel to one another to be provided the control device 1 is embodied in such a way that the microcontroller 13 ensures that adjustment data items d are stored in the non volatile memory unit 10 and triggered by a triggering process the triggering process can for example be in the form of a defined time interval u03b4t this means that during a movement of the adjustment element e along the adjustment path x the respectively current adjustment data items d are stored in the memory unit 10 after the defined time periods u03b4t this ensures that in particular after a voltage dip or after a resetting of the microcontroller 13 destandardization with regard to the position of the adjustment element e of the adjustment apparatus v does not occur furthermore the microcontroller 13 can have an algorithm for simulating the run on behavior of the adjustment element e after a voltage dip and or after a voltage failure as a result it is also possible to prevent destandardization of the adjustment apparatus if the moving adjustment element e runs on for a certain distance of the adjustment path x because of its inertia even after the assigned drive has been switched off before said adjustment element e is braked to a standstill the second embodiment of the control device 1 which is shown in fig2 corresponds in terms of its design comprising the timer 11 the microcontroller 13 the volatile.
