A motor control device in which, when an operator sets a change-over setting section (3), letters and scales of the change-over setting section (3) are illuminated to improve visibility, facilitating setting and preventing a setting mistake, and which can be reduced in size. The motor control device has illumination light sections (11a, 11b) for illuminating the change-over setting section (3), an illumination light drive section for driving the illumination light sections (11a, 11b); and a control section for controlling the drive and stop of the illumination light drive section. The illumination light sections (11a, 11b) can be turned on and off based on a change in a set value at the change-over setting section (3).
