The invention relates to a method for optimizing the number of workstations, which can be supplied with additional vacuum simultaneously on account of circuits, of a textile machine which has a multiplicity of workstations, wherein the textile machine has a vacuum system with at least one vacuum assembly, the vacuum output of which can be increased via the rotational speed of its drive motor, regulated by monitoring of the vacuum level, until a maximum rotational speed is reached. There is provision according to the invention for a value for a rotational speed reserve to be calculated from the known maximum rotational speed of the drive motor of the vacuum assembly, which maximum rotational speed defines the maximum vacuum output of the vacuum system of the textile machine, and from a prevailing actual rotational speed of the drive motor of the vacuum assembly, which actual rotational speed results from the current vacuum requirement of the textile machine, using which value for a rotational speed reserve the number of workstations is determined which can still be supplied with additional vacuum. A maximum number of workstations which can be supplied simultaneously with additional vacuum is determined from this number, increased by the number of workstations which are currently already being supplied with additional vacuum on the basis of the actual rotational speed of the drive motor, and vacuum requirements are rejected which exceed this maximum number of circuits. |
