Filter switching method for a machine control system
The invention relates to a method (100) for switching between desired value filters (26, 28) of a drive means (52) for a machine axis (10, 12) during operation. An input signal (20) is applied to the first and to the second desired value filter (26, 28) for producing a first and a second output signal (23, 33). Then any deviation between the first and the second output signal (23, 33) is determined. If the deviation falls below a threshold value, the first desired value filter (26) is separated from the drive means (52) and substantially simultaneously the second desired value filter (28) is connected to the drive means (52). The desired value filters (26, 28) have different running times (19).
