<P>PROBLEM TO BE SOLVED: To provide a vibration detector of feedback control system and motor control system having the same, capable of preventing generation of noise and damage to machinery by precisely detecting a vibration state and promptly finding an abnormal state even after a moment of inertia of a motor or load deviates. <P>SOLUTION: The present invention relates to a vibration detector of a control system that controls a motor connected to a load. The control system includes a control unit that feedback-controls an object to be controlled and controls the motor, and a vibration state determination section that determines the generation of vibration on the basis of upper and lower limit peak values of an output of the control system and occurrence time thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
