Document Type and Number:
Japanese Patent JP5617460
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a jam decision provided with a threshold value to driving force which drives a control object, in the jam decision of a servo mechanism.SOLUTION: There are provided: a speed measurement part which measures a speed of a driving body; a target speed holding part 303 which stores a target speed at which said driving body is driven; a drive control part which carries out drive control of a DC motor in accordance with a difference between the speed measured by the speed measurement part and the target speed stored in the target speed holding part when executing voltage control or PWM (Pulse Width Modulation) control; and a motor torque malfunction detection part 301 which detects that motor torque has become an abnormal value by an interference of said driving body with a foreign substance in the case where the DC motor is made to be driven by the drive control part. The motor torque malfunction detection part 301, based on a value calculated from the number of rotations of the DC motor and the voltage or a PWM control Duty ratio, detects that the motor torque is the abnormal value.
