Calibration enables the server to correct for any mechanical errors inherent in the
system. Mechanical components, such as the leadscrew and linkages, can be
machined only within a certain tolerance, e.g. the leadscrew may be nominally 1mm
but actually 1.0005mm, giving a 0.5 micron error. In practice, these errors accumulate
from a number of sources, however they are repeatable and therefore, can be
compensated.
During calibration, the total positional error is measured at a large number of points
and these errors are stored as a look up table (LUT). The LUT is saved as a
calibration file, one file for each particular stage. Whenever the stage is moved, the
LUT is consulted to ascertain the precise movement required to achieve the
demanded position.
A calibration file is shipped with each unit. The use of a calibration file is optional.
Without it, the repeatability and resolution of the stage are unaffected, but no
compensations are made to enhance the accuracy.
To assign a calibration file:
1) Click the ‘Enabled’ Checkbox.
2) Click the folder icon and navigate to the location of the required calibration file.
3) Select the file so that the file name is displayed in the ‘Calibration File’ field.
4) Click OK.
