The invention concerns a process and a device for zeroing a spindle, in particular a rotating spindle, using a zeroing sensor (4) set up on the spindle (2). The invention also calls for a position-measurement system (1) which generates perfectly cyclic signals internally and by means of which the zero mark on the spindle is approached and the local, perfectly cyclic position value read and fed to the spindle-control unit (16). From this, the distance to the desired position is calculated in the spindle-control unit (16), and the spindle (2) brought automatically or by hand into this position. Zeroing is carried out by the zeroing sensor (4) in this position, which lies at the centre of a selectable sensor cycle of the position-measuring system. |
