the magnetic bearing 6 and can be read out by means of the computer unit 20 from the control unit 4 by means of the communication interfaces 18 19 of the control unit 4 and the interface 24 of the external computer unit 20 for adjustment purposes and displayed by the computer unit 20 the external computer unit 20 allows an operator to adjust the bearing even before being put into operation for the first time without the spinning station 33 itself having to be put into operation the adjustment is simplified by using a suitable application which converts the data detected and visually displays them using the external means of the system according to the invention in conjunction with one of the communication interfaces 18 or 19 of the control unit 4 the signals of the rotor drive 31 can be read out for the checking thereof and can be displayed or adjustments can be carried out in this context it being possible to carry this out both during operation of the rotor drive 31 with the spinning station control unit 35 active or deactivated and also directly after the production of the rotor drive 31 independently of the rotor spinning machine 30 as a result adjustment and maintenance work on the individual spinning stations 33 of the rotor spinning machine 30 are therefore suitably facilitated as a whole by the system according to the invention it will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application many embodiments and adaptations of the present invention other than those herein described as well as many variations modifications and equivalent arrangements will be apparent from or reasonably suggested by the present invention and the foregoing description thereof.
