Abstract

PURPOSE: To quickly detect the anomalous state such as an irregularity of a device, the disconnection of a power source circuit and the like by a method wherein the generation of an anomalous state of control of the titled induction motor is detected under the condition in which the primary current comes down lower than the prescribed value while the motor is being operated.
CONSTITUTION: When an anomalous state is generated in the titled device or a power source circuit and the direct current signal 12a outputted from a three- phase full-wave rectifier 12 is made smaller than the reference signal 14a of the reference setting device 14, the output signal 13a of a comparator 13 is turned to a logical value '0'. Accordingly, the inversion signal 21a of the output signal of the comparator 13 outputted from an inversion circuit 21 is turned to '1', the output signal 17a of an AND circuit 17 is turned to '1', and the anomalous state of control in operation can be detected by the abnormal state detecting signal 20a outputted from an OR circuit 20.
