Segmented Linear
Error Correction
(SLEC)
Scroll through the Setup menu to highlight Segmented Linear
Error Correction (SLEC). Linear error correction coefficients are
applied to segments of each axis to compensate for encoder and
machine travel variations. The standard is measured on each axis,
and the measured values are compared to the nominal values to
generate correction coefficients. Correction coefficients are gen-
erated for each segment that deviates from the nominal value.
The correction coefficients are then used to provide linear com-
pensation for only the segments requiring it.
Mount the standard on the stage and zero axes on the datum of
the standard. Measure and graph the nominal and actual seg-
ment values as shown below. A segment is any group of points
that combine to form a straight line.
