  • the preferred direction of rotation is preset, for example, as a clockwise rotation.
  • the user can specify the preferred direction of rotation (1230 in Fig. 14 ) can be programmed.
  • the interactive program 1342, 1344 preferably monitors the at least one operating element 106, preferably via a sensor unit (1370 in Fig. 15 ), which preferably has a mechanical, electrical, magnetic and / or optical sensor. If the interactive program 1342, 1344 detects, preferably via the sensor unit 1370, a movement of the operating element 106 from a stable rest position (510 in Fig. 5 ) to an unstable switching position (520 in Fig. 5 ), which corresponds to answer A to test 1910 and can be done, for example, by a user 1230 actuating the operating element 106, the interactive program 1342, 1344 continues with step 1930.
  • the interactive program 1342, 1344 does not move the operating element 106 from a stable rest position (510 in Fig. 5 ) into an unstable Switch position (520 in Fig. 5 ) detects which corresponds to answer B to test 1910, then the interactive program 1342, 1344 continues with test 1920.
  • the interactive program 1342, 1344 detects, preferably via the sensor unit 1370, a movement of the operating element 106 from the unstable switching position 520 back to the stable rest position 510, which corresponds to response C to test 1920 and preferably by at least one spring element (610 in Fig. 6 ) is enabled, the interactive program 1342, 1344 continues with step 1930. If the interactive program 1342, 1344 does not detect any movement of the operating element 106 from an unstable switching position 520 to a stable rest position 510, which corresponds to response D to test 1920, then the interactive program 1342, 1344 returns to step 1902.
  • step 1930 the interactive program 1342, 1344 monitors the status of the drive motor 120 and proceeds to test 1960 if the drive motor 120 is out of order, which corresponds to response E to test 1940. If the drive motor 120 is operating, which corresponds to answer F to test 1940, the interactive program 1342, 1344 continues with step 1950.
  • the interactive program 1342, 1344 preferably brakes the drive motor 120 to a standstill. If the drive motor 120 is out of operation or at a standstill, the interactive program in step 1970 effects a switching process for switching the drive unit 220 between the first and second directions of rotation. If the drive unit 220 was driven clockwise before step 1970, for example, then the drive unit 220 is driven counterclockwise after step 1970. If the drive unit 220 was driven in the counterclockwise direction before step 1970, for example, the drive unit 220 is driven in the clockwise direction after step 1970. Furthermore, in step 1970, the interactive program preferably controls a display - for example display 1014, 1016 on display 1010 in FIG Fig. 16 and / or displays 1185, 1185 on control unit 1120 in Fig. 14 - To display the current direction of rotation of the output spindle 310 of Fig. 3 .
  • the interactive program proceeds to step 1990 upon completion of the toggle, during which the interactive program prefers 1342, 1344 enables the drive motor 120 to be started up again and returns to step 1902.
