A motor drive control device includes: a deceleration start position calculating unit that calculates a deceleration start position indicating an address at which a pulse period is stored, the pulse period being equal to or larger than a pulse period at the time of forced stopping and closest to the pulse period at the time of forced stopping among the pulse periods included in a driving information; a stop pulse number calculating unit that calculates the number of pulses required for stopping the motor at an exciting position; and a driving control unit that outputs a total number of pulses of a counted number of pulses and the number of pulses from the deceleration start position until the motor is stopped in forcibly stopping the motor, and outputs a shortage of the number of pulses required for stopping the motor calculated by the stop pulse number calculating unit.
