Abstract (en)
[origin: EP0734932A2] The monitoring device has test signals supplied to the AC leads (A1,...A4)for the operating drive, with detection of corresponding signal parameters dependent on the position of the operated device, the operating drive, or the condition of the AC leads for evaluation via a microprocessor by comparison with expected values. The test signals are generated by a network containing the AC leads, the drive windings (W1,W2,W3) and a signal generator (SG), with detection of the measuring signal parameters via characteristic electromagnetic values.
