Entering 
compensation 
values
The following information must be entered in the <*.COM> tables:
 In the AXISPOS column, enter the compensation points for the 
compensation values. The positions are given with respect to the machine 
datum (MP_refPosition).
 If required, enter the compensation values measured in the negative 
direction of traverse in the BACKLASH column.
 Enter the compensation values to which the compensation points belong in 
the column of the axis for which a dependency relationship exists. The 
name of the column is the name from CfgAxes/axisList (see Table Format).
Example: The following dependencies apply to the Y axis and Z axis:
 Ball screw pitch error in Z and Y: Z = F(Z) and Y = F(Y)
 Axis sag in Z depending on Y
 Range of traverse: Z axis = 800 mm, Y axis = 500 mm
 Start point for compensation values: Z = –200 mm, Y = –90 mm
 Desired spacing of compensation points: 5 mm
Number of compensation points:
