Abstract
The invention provides a servomotor controller that makes it possible to reduce compensation delay even when a dead band is provided. The servomotor controller includes a motion acquiring unit that acquires a motion of the servomotor, an acceleration amount acquiring unit that acquires an acceleration amount of the servomotor, a compensating unit that compensates a motion of the servomotor, and a compensation start determining unit that determines a start of the compensation by the compensating unit responsive to the motion of the servomotor, wherein the compensation start determining unit has a dead band unit that sets a dead band range which is a range of a predetermined value relative to the motion of the servomotor, and the dead band unit changes the dead band range based on the acceleration amount acquired by the acceleration amount acquiring unit.
