PROBLEM TO BE SOLVED: To suppress the deterioration of control characteristics when this servo controller is used in an environment where there are many noises by quickening the convergence of the estimated error of a command position to be generated when any data abnormality is generated. SOLUTION: This servo controller is provided with an update timing detecting means 16 for detecting a timing in which command position data are updated and an interpolating means 18 for interpolating command position data to be updated in each NC arithmetic cycle according to a servo operation cycle. When the command position data received in the non-update timing of data are normal, and the command position data are abnormal in the previous update timing, the re-operation of the interpolation processing is performed.
