Method involves: <??>(a) Cyclical sampling, processing and linking of measurement signals to form common control value (m) for each cycle <??>(b) determination of upper and lower thresholds based on statistical evaluation of previously stored control values <??>(c) comparison monitoring of respective control values with thresholds <??>(d) generation of fault signal if control value lies outside threshold. <??>Steps a-d are repeated in position, speed or acceleration regulation. <??>The invention also relates to a corresponding computer program and digital switchgear. |
