Abstract:
1. A method for determining a zero position of a yarn guide device of a winding device of a textile machine which is operative for cross-winding a yarn by means of a step motor for producing yarn cheeses, the method comprising the steps of displacing an element of the yarn guide device by the step motor in the direction of the zero position, and positioning the element of the yarn guide device at a comparatively slow speed against a defined detent arranged downstream of the zero position in the direction of the displacement, switching off the step motor for positioning a rotor of the step motor into one of two possible stop positions, and then switching on the step motor by a definite electrical current supply to stator windings of the step motor such that, when again switched off, the rotor of the step motor is in the stop position in which the yarn guide is in its zero position.
