The compensation table is now included in the calculation of the compensation value
for the compensation axis.
The compensation axis $AN_CEC_OUTPUT_AXIS can be taken from the table configuration.
The effective total compensation value in the compensation axis can be adapted to the
current machining by the targeted activation of tables (from NC part program or PLC
user program).
The function does not become active until the following conditions have been fulfilled:
● The option "Interpolatory compensation" is set
● The associated compensation tables in the NC user memory have been loaded and
enabled (SD41300 $SN_CEC_TABLE_ENABLEt] = 1)
● The
current position
measuring system is referenced (NC/PLC interface signal DB390x
DBX0.4 / .5 (Referenced/synchronized 1 or 2) = 1).
0: The evaluation of the sag compensation table [t] is not enabled.

Description: The compensation value stored in the table [t] is multiplied by the weighting factor.
When selecting the weighting factor it should be ensured that the total compensation
value in the compensation axis does not exceed the maximal value of
(MD18342 $MN_CEC_MAX_SUM). With [t] = index of the compensation table (see MD18342
$MN_MM_CEC_MAX_POINTS)
If, for example, the weight of the tools used on the machine or the workpieces to be
machined
are too
different and this affects the error curve by changing the amplitude,
this can be corrected by changing the weighting factor. In the case of sag
compensation, the weighting factor in the table can be changed for specific tools or
workpieces from the PLC user program or the NC program by overwriting the setting data.
However, different compensation tables are to be used if the course of the error curve
is substantially changed by the different weights.
