A motor-controller device includes a position control system that controls the position of a machine end connected to the motor. The motor-controller device receives a first speed directive from a high-level controller, stored in the position control system to output a motor axis position response to the high-level controller, including speed controller and vibration controller in speed control system. The vibration controller includes a position-command estimator that calculates an estimate of the location directive based on the first speed directive and the motor axis position response, a parallel vibration damping controller that extracts frequency components that excite vibration of the machine end included in the first speed directive based on the estimated value of the location directive, and outputs the extracted frequency components.
