Abstract: A textile machine includes a main driven system driven by a plurality of main motors, a plurality of slave driven systems each driven by at least one slave motor, and an energy supply/control arrangement for supplying energy to the main motors and the slave motors and for controlling the flow of energy between a power supply system and the main motors and the slave motors. The energy supply/control arrangement includes a first energy exchange unit, a first main motor unit, a second energy exchange unit, a second main motor unit, and a controller. The slave motors include at least one first slave motor connected to a first DC voltage bus system by an associated first slave motor unit and at least one second slave motor connected to a second DC voltage bus system by an associated second slave motor unit.

Abstract: A method and a device for bringing a textile machine to a controlled standstill in the event of a failure of the power supply, and a correspondingly equipped textile machine, the textile machine having at least two axes that are driven in synchronization by respective electric motors (M1-M5) connected to a common intermediate voltage circuit (1), and in which at least one electric motor acting as power generator can supply electric power to at least one other electric motor via the common DC bus (1), and in which the voltage (V) on the common DC bus is controlled by varying at least two variables in such a way that the voltage follows a previously defined curve while the textile machine is being brought to a standstill.
