Abstract
Provided is a motor control device which realizes automatic adjustment of control of a motor for driving a mechanical load through a simple operation. The motor control device includes: a follow-up control unit () for receiving detection information of a detector () to output a torque command signal and output a status of motor control of a motor () as a control status amount signal, when a command signal regarding the motor control to be output from an upper-level controller is absent; an oscillation detection unit () for receiving the control status amount signal and detecting oscillation of a control status amount to output an oscillation detection signal; and an automatic adjustment unit () for receiving the oscillation detection signal to monitor a control status of the motor () and adjust a control parameter of the follow-up control unit () only when abnormality is detected.
