A motor control device includes a first position detecting unit for detecting a position of a movable part, a second position detecting unit for detecting a position of a driven part, an error computing unit for computing an error between a first position detection value detected by the first position detecting unit and a second position detection value detected by the second position detecting unit, a memory unit for memorizing, as an initial error, an error computed when the movable part engages with the driven part, a compensation amount computing unit for computing a backlash compensation amount for compensating backlash, a compensation gain computing unit for computing a compensation gain based on the acceleration command, and a compensation amount computing unit for computing the backlash compensation amount using the compensation gain.
