Example
The following example shows compensation value inputs for machine axis X1 as a program.
%_N_AX_EEC_INI
CHANDATA(1)
$AA_ENC_COMP[0,0,X1]=0.0 ; 1. compensation value (interpolation point 0)
+0 mm
$AA_ENC_COMP[0,1,X1]=0.01 ; 2. compensation value (interpolation point 1)
+10 mm
$AA_ENC_COMP[0,2,X1]=0.012 ; 3. compensation value (interpolation point 2)
+12 mm
...
$AA_ENC_COMP[0,120,X1]=0.0 ; last compensation value (interpolation point
120)
$AA_ENC_COMP_STEP[0,X1]=2.0 ; distance between interpolation points 2.0 mm
$AA_ENC_COMP_MIN[0,X1]=-200.0 ; compensation starts at -200.0 mm
$AA_ENC_COMP_MAX[0,X1]=40.0 ; compensation ends at +40.0 mm
$AA_ENC_COMP_IS_MODULO[0,X1]=0 ; compensation without modulo function M17
Values for more than 350 interpolation points result in alarm 12400 "Element does not exist".
