| Abstract |
An opportunity to substitute mechanical gear systems in packaging machines by a system of intelligent single drives in order to get more flexibility will be presented in this paper. The single drives are coupled via a serial bus. Starting from a definition of basic functions of an intelligent drive, a practical realization will be presented. This section includes a short description of the used control structure, a possibility of reference generation and the used thermal model for monitoring the drive temperature too. The features of the bus system used for the coupling of the drives are discussed in a following section. Tools for the description of such a drive system are necessary for its design, simulation and starting up and can be based e.g. on a function chart. Last but not least a pouch-, form-, fill- and seal-machine equipped with a system of intelligent single drives is presented. |
