摘要: A rotary encoder includes two first detection units disposed at positions that are symmetrical about a rotation axis, each of the outputting an incremental signal, and second unit outputs absolute signal φ . The storage stores plurality formulas for correcting errors signals, being different from other in accordance with , generated due to eccentricity; calculation calculates corrected phase I by performing operation on signals using one corresponding ; generation generates angle scale basis
