METHOD FOR OPERATING A TEXTILE MACHINE PRODUCING CROSS-WOUND BOBBINS AND TEXTILE MACHINE PRODUCING CROSS-WOUND BOBBINS

摘要

The invention relates to a method for operating a textile machine (11) producing cross-wound bobbins and to a textile machine (11) producing cross-wound bobbins with a large number of similar workstations (1), which in each case have a plurality of individual drives configured as stepping motors (6, 55, 56, 51, 5% 59) to drive handling devices (4,17, 23, 24, 60, 27) of the workstation (1), each stepping motor (6,55,56, 57, 58, 59) being allocated a power output stage (6a, 55a, 56a, 57a, 58a, 59a), by means of which a desired value for the absolute value of the current is adjusted. According to the invention stepping motors (6, 55, 56, 57f 58, 59) of a plurality of workstations (1) are fed by a power supply unit (31) with limited power and a variable, which represents rotational speed fluctuations, at least of the stepping motors (6, 55, 56, 57, 58, 59). of a handling device (4,17, 23, 24, 60, 27) of the large number of workstations (1) is detected, the desired value for the absolute value of the current of these stepping motors (6, 55, 56, 57, 58, 59) is adapted depending on the variable, which represents the rotational speed fluctuations, and the power received from the power supply unit (31) is thereby limited.
