4.4.4.3 Example
The direction-dependent compensation tables of the X axis are shown in detail for a three-
axis machine in the fallowing example:
Configuring
Number of compensation interpolation points:
MD18342 $MN_MM_CEC_MAX_POINTS[0] = 11 (Table 1: Axis X, positive traversing
direction)
MD18342 $MN_MM_CEC_MAX_POINTS[1] = 11 (Table 2: Axis X, negative traversing
direction)
Note
It is not necessary to define the number of interpolation points for SINUMERIK 828D,
because when enabling the "sag compensation, multi-dimensional" option, immediately eight
tables each with 200 interpolation points per table for the compensation are available. This
cannot be extended!
