Measures for the automatic adjustment of the controller parameters. The majority of operations that are necessary for the re-optimisation of can be defined in schemas and described by formula-based relationships. In this way they can be transferred to a microcomputer that then automatically undertakes the identification, configuration and optimisation of a controller directly on the drive.
The trimming of hydraulic controllers in general takes a large amount of time, because it must be undertaken on the finished machine. For this reason automatic retrimming makes the task significantly easier.
