A system for determining a zero position of a yarn guide () of a textile winding device for cross-winding yarn into cheeses via a step motor (). The yarn guide (), acted upon by the step motor (), is initially displaced in the direction of its zero position (NS) and positioned at a slow speed against a defined detent () downstream of the zero position (NS). Then, the step motor () is switched off, causing the rotor () of the step motor () to drop into one of two possible stop positions (RS, RS). Subsequently, the step motor () is switched on by an electrical current supply to its stator windings (A,B) such that, when switched off, the rotor () of the step motor () is in the stop position (RS) in which the yarn guide () is in its zero position (NS).
