Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method and device for compensating a frequency shift of an encoder.SOLUTION: The method for compensating a frequency shift of an encoder includes a step (100) for deciding the value of a frequency of an input encoder signal, a step (130) for determining a value of the frequency shift by analyzing a clock signal of an encoder index and the input encoder signal, and a step (150) for generating a clock with compensated frequency shift by compensating the value of the frequency shift. The method for compensating a frequency shift of an encoder is executed for each of functions and operations in different devices, and can be used as a component connected by wiring or printed circuit boards.
