Abstract:
1. A process for a recognition of a polyphase machine connected to a converter comprising a stator and a rotor, the process comprising: (a) connecting the polyphase machine with several electric phases to the converter; (b) supplying of a first test signal from the converter to at least one of the several electric phases of the connected polyphase machine; c) measuring of at least one causal consequence of the first test signal as a measured result; (d) evaluating the measured result as a causal consequence in order to obtain a first measuring value (r (e) repeating of at least once steps (b) to (d) for at least one further test signal and obtaining at least one further causal consequence and at least one further measuring value (r (f) allocating of these at least two measuring values to a comparison function; (g) comparing the comparison function with at least one of several reference functions, each of which representing one type of a polyphase machine to select the reference function which is most similar to the reference function; (h) providing one of several available system programs in a control section of the converter in accordance with the selected reference function; to adapt the converter to the machine supplied by the converter.
