Abstract
A motor controller capable of more reliably starting a stepping motor even if a predetermined drive power is supplied to the stepping motor, and to a control method for the stepping motor is provided. The motor controller driving a stepping motor detects that the stepping motor is in a step-out state after a start operation of the stepping motor is performed. If predetermined determination conditions are satisfied, when it is detected that the stepping motor is in a step-out state, it is determined that a restart operation of the stepping motor is performed, and the stepping motor is restarted.
