  • System and method for detecting abnormal state of velocity outputted from motor
    Patent number: 10153722
    Abstract: A system includes a control module, a velocity-detecting module and a state-analyzing module. The control module generates a control command to control the servo drive system, and bases on the control command to define angular-acceleration standard ranges with respect to detection times. The velocity-detecting module detects output angular-velocity values of the servo motor with respect to detection times upon when the servo motor is driven. The state-analyzing module includes a processing unit and an abnormal-state judging unit. The processing unit stores the output angular-velocity values, and bases on the output angular-velocity values to calculate output angular-acceleration values with respect to the detection times. The abnormal-state judging unit determines whether or not each of the output angular-acceleration values with respect to each of the corresponding detection times is within the respective angular-acceleration standard range and thereby to generate corresponding comparison results.
