A gray code signal with a remainder of 76 is used for a resolution of 360 per rotation and a gray code signal with a remainder of 152 is used for a resolution of 720 per rotation. Therefore, the code signal for a resolution of 360 per rotation uses addresses 76 through 435 and that for a resolution of 720 per rotation uses addresses 152 through 871. 2. The electrical maximum response rotation is determined by using the resolution and maximum response frequency in the fol- lowing formula. Maximum response frequency Electrical maximum response rotation (rpm) = x 60 Resolution Therefore, a signal cannot follow electrically if the actual rotation exceeds the maximum response rotation. 2
