<P>PROBLEM TO BE SOLVED: To provide a motor drive device that prevents a continuous rotation fault of a motor. <P>SOLUTION: A motor drive device 10 includes a motor controller 11 which outputs a command value D0 for driving a motor 18, and a motor drive module 12 for driving the motor 18 based on the command value D0. The motor drive module 12 includes a command value change detection unit 13 for detecting whether the command value D0 has been changed; and a command value correction unit 14 for correcting the command value D0. When the command value D0 has not been changed within a predetermined period of time, a corrected command value D1, which is a command value D0 corrected in a direction decelerating the motor 18, is derived by the command value correction unit 14, and the motor 18 is driven by the corrected command value D1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
