SERVO-DRIVE DEVICE FOR NC CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a servo controller equipped with the setting function of a servo-control parameter for properly setting a servo-control parameter even when device configurations are changed. SOLUTION: The NC controller for performing servo-control is provided with: an operation pattern output part 11 for commanding the predetermined same operation pattern by changing frequency; storage parts 10 and 12 for storing command data and response data; a frequency characteristic preparation part 13 for calculating the frequency characteristics of a gain from command data and response data; a characteristic extraction part 14 for extracting the characteristics of the prepared frequency characteristics; and a parameter preparation part 15 for replacing the value of a servo-control parameter until the gain enters a predetermined range.
