PURPOSE: An encoder correction method and a device thereof are provided to re-correct wrong correction caused by a discontinuous section when applying power in a continuous section, thereby minimizing correction errors caused by the discontinuous section. CONSTITUTION: An encoder correction method is as follows. If an absolute position encoder of a servo motor is a discontinuous section, error flags are set and are notified to a user(S12,S14). If the absolute position encoder is out of the discontinuous section, a relative position encoder is corrected(S16). [Reference numerals] (AA) Start; (BB) End; (S10) Apply power; (S12) Absolute position encoder is in a discontinuous section?; (S14) Set an error flag and notify a user; (S16) Correct the absolute position encoder; (S18) Recorrect a relative position encoder using the value of the absolute position encoder |
