Note1: Please take care that the accuracy listed above is the typical amount and it is not
guaranteed.
Note2: The amount of the accuracy mentioned above does not include the influence of
the error caused by the radial eccentricity in the installation of the detection ring.
The error amount caused by the radial eccentricity in the installation of the detection ring
is calculated as follows.
Error amount (deg.)=360A(mm)/B(mm)
A: Radial eccentricity of the machine spindle or sleeve in the area where the
detection ring is installed.
B: Length of the outer diameter of the detection ring
e.g. In case that the radial eccentricity of the spindle is 0.005mm with the
256λ detection ring (outer diameter: φ103.2), the error amount is;
0.005X360/(103.2Xπ)=0.0055(deg.)
