Compensation (K3)
11.3 Interpolatory compensation
Table parameters
The position-related corrections for the relevant compensation relationship are stored as
system variables in the compensation table.
The following parameters must be set for the table:
● Compensation value for interpolation point N of compensation table [t]
● Basic axis $AN_CEC_INPUT_AXIS[t]
● Compensation axis $AN_CEC_OUTPUT_AXIS[t]
● Distance between interpolation points $AN_CEC_STEP[t]
● Starting position $AN_CEC_MIN[t]
● End position $AN_CEC_MAX[t]

$AN_CEC [t, N]; t = 0, 1, N = 0 to 349
The compensation value of the compensation axis must be entered in the table for each
individual interpolation point (position of the base axis).
Name of machine axis whose setpoint is to be used as the input for the compensation
table [t].
Name of machine axis to which the output of the compensation table [t] is to be applied.
The distance between interpolation points defines the distance between the input values
for the compensation table [t].
The initial position is the base axis position at which the compensation table [t] begins (≙
interpolation point 0).
The compensation value for the initial position is $AN_CEC [t,0 ].
The compensation value of interpolation point 0 is used for all positions smaller than the
initial position (exception: table with modulo functions).
The end position is the base axis position at which the compensation table [t] ends (≙
interpolation point k).
The compensation value for the end position is $AN_CEC [t,k].
The compensation value of interpolation point k is used for all positions larger than the
end position (exception: table with modulo functions).
The number of required interpolation points is calculated as follows, where 0 ≤ k < 350:
