Abstract

PURPOSE:To realize the simple and quick diagnosis for a fault of a driving part or a step motor, by carrying out the diagnosis based on the fault of a current waveform of the drive signal supplied from the step motor. CONSTITUTION:The prescribed frequency signal is applied to a step motor via a quartz oscillator to produce a drive current at a drive coil of the step motor. The drive current waveform in accordance with the starting voltage is detected to detect the fault of adjustment between the rotor and the stator of the step motor as well as the fault of the wheel train by the drive current waveform corresponding to the drive voltage. In such way, the fault of the drive part can be diagnosed in a simple and quick way.
