Abstract

The invention provides a control circuit and a method for qualifying a fault for a synchronous machine. The control circuit () is designed with: a rotor position angle range determination device () which is designed to determine at least one rotor position angle range covered by a rotor of the synchronous machine; a diagnostic signal determination device () which is designed to determine at least one diagnostic signal value of a diagnostic signal which indicates a fault; a comparison device () which is designed to determine whether a predetermined diagnostic threshold () is exceeded by the at least one determined diagnostic signal value or a diagnostic signal value derived from the at least one diagnostic signal value; and a qualification device () which is designed to qualify the fault, which is indicated by the diagnostic signal, on the basis of the at least one covered rotor position angle range and the exceeding of the predetermined diagnostic threshold () by the diagnostic signal value or the derived diagnostic signal value.
