Configuring segmented linear error compensation (SLEC)
For a segmented linear error compensation (SLEC), you divide the axis into short
segments by defining up to 200 supporting points. The deviations between the
actual distance traversed and the segment length in the individual segments
determine the compensation values that compensate the mechanical influences
acting on the axis.
