  • Dynamic displacement error compensation system
    Patent number: 11512984
    Abstract: A dynamic displacement error compensation system by which detection error information obtained based on calibration detection of first and second axes, is respectively made into first and second compensation tables for compensating displacement on the axes by using positional information of the axes as variables, the first compensation table is stored in a first driver of a first motor device for driving a first moving element to move linearly on the first axis, the second compensation table is stored in a second driver of a second motor device for driving a second moving element to move linearly on the second axis, the drivers simultaneously or successively obtain a first dynamic positional information of the first moving element on the first axis and a second dynamic positional information of the second moving element on the second axis, and the moving elements are respectively displaceably compensated according to the compensation tables.
