Abstract
A motor driving control apparatus in the embodiment includes: a first controller configured to control powering and regeneration of a motor; a second controller configured to control the first controller; and assistant circuitry configured to activate the second controller in a stop state, when a counter electromotive force caused by the motor, which is rotated without control by the first controller, satisfies a predetermined condition, before a power-on instruction for the motor driving control apparatus is made or in a state where the power-on instruction for the motor driving control apparatus is not made.
