Error detection values
This value is for confirming the accuracy of calibration result.
Output the error detection values when the Stage has θ-axis.
T
his value is calculated using a calibra
tion data calculated in Master calibration and a measurement result
sampled rotation movement.
If a problem of magnification, axis angle or center position
of r
otation is occurred, this value may be larger.
In the followings, describe the calculation
method in the case of sampling time is 2 as an example.
1) Rotation sampling is executed based on
sampling settings. A reference position
may change depending on sampling
method.
2) Calculates the center position of rotation
fr
om sampling result.
3) Calculates the reverse rotation point from
the calcul
ated rot
ation point each of
sampled points.
