<P>PROBLEM TO BE SOLVED: To provide a motor control device and a control method, capable of avoiding such a dangerous state that a motor vibrates and runs out of control, even when a servo system becomes unstable under any condition. <P>SOLUTION: The motor control device includes an oscillation detector 103, which detects the oscillation state of a drive system, a limit operation part 5, which limits a torque command uref to a preset limit value TLIMT or under, a changeover switch 1, which outputs a torque command uref via the limit operation part 5, only while the oscillation detector 103 detects the oscillation and judges that the motor is vibrating, and a changeover switch 2, which switches off the input to an integrating controller 3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
