Abstract:
A servo control apparatus includes: a model-response calculating unit; a motor-end-movement-amount-during-stopping measuring unit that measures a motor end movement amount during stopping, which is a displacement amount of a detection value of a motor end position in a period from when the calculated value of the machine end position changes to zero until the calculated value changes to a value other than zero; and an error-correction-amount calculating unit that calculates an error correction amount on the basis of a parameter in which a maximum change amount of a deviation between the machine end position and the motor end position during moving direction reversal is set in advance, the calculated value of the machine end position, and the motor end movement amount. The servo control unit sets the detection value of the machine end position and the detection value of the motor end position.
