<p>This detected position correction method includes: a first step of mounting an electromagnetic inductance-type position detector (22) and a master position detector (23) to a moving body (21); a second step of positioning the moving body so that the detected position for the electromagnetic inductance-type position detector is at the 0 position; a third step of resetting the detected position of the master position detector to the 0 position; a fourth step of calculating the detected position error, which is the difference between the detected position of the electromagnetic inductance-type position detector and the detected position of the master position detector after moving the moving body, and acquiring the detected position error and detected position of the electromagnetic inductance-type position detector at fixed interval positions; a fifth step of performing FFT analysis on the acquired data; and a sixth step of extracting, from the FFT analysis results, an error corresponding to the natural period of the error variation and storing the same in a storage means. By implementing these and other steps and then performing inverse FFT analysis on the stored data, the detected position of an electromagnetic inductance-type position detector is corrected.</p> |
