Abstract

A motor control apparatus according to one aspect of the present invention is configured to be connected to a motor by a wiring line, and includes: a motor driving unit for driving a motor; a current command unit for commanding supply of current to the motor driving unit; and, a miswiring detecting unit for detecting miswiring of lines connected to motors by acquiring via wiring lines a signal indicating the motor temperature detected by a motor temperature detector provided for the motor, wherein the miswiring detecting unit detects presence or absence of miswiring of the wiring lines, based on the change of the motor temperature when the current command unit commands supply of reactive current to the motor driving unit.
