摘要

A method for operating an open nend - rotor spinning unit with individual drive chem electric drive of the spinning rotor, wherein said with respect to the rotational speed of the different phases of the spinning rotor in accordance with predetermined functions of which are controlled, characterized in that the electrical energy which is supplied to the drive is continuously detected that the actual value - course of a variable which represents the supply of energy with which the respective operating phase associated reference value - course is compared continuously and in that in the case of exceeding of limit values of the deviation of the drive is switched off.
