Compensation table for sag compensation of the Y1 axis
The following example shows the compensation table for sag compensation of the Y1 axis.
Depending on the position of the Y1 axis, a compensation value is applied to the Z1 axis.
The 1st compensation table with index = 0 is used for this.

$AN_CEC_STEP[0]=8 ; distance between interpolation points 8.0 mm
$AN_CEC_MIN[0]=-400.0 ; Compensation starts at Y1=-400 mm
$AN_CEC_MAX[0]=400.0 ; Compensation ends at Y1=+400 mm
$AN_CEC_DIRECTION[0]=0 ; Table applies for both directions of travel of Y1.
$AN_CEC_MULT_BY_TABLE[0]=0 ;
$AN_CEC_IS_MODULO[0]=0 ;compensation without modulo function

For this example, the configured number of interpolation points must be ≥ 101:
MD18342 $MN_MM_CEC_MAX_POINTS[0] ≥ 101
The memory required in the static user memory is at least 808 bytes (8 bytes per
compensation value).
