Example

The following examples shows parameterization of the directional compensation tables for an
axis (machine axis AX1). All parameter values of the compensation tables are written by means
of a program.
Compensation parameters
● Basic axis = compensation axis = machine axis AX1
● Distance between interpolation points: 58.0 mm
● Starting position: -585.0 mm
● End position: -5.0 mm
Table definition
The 1st and 2nd compensation table are defined with 11 compensation interpolation points
each for machine axis AX1 as directional compensation tables:
● MD18342 $MN_MM_CEC_MAX_POINTS[ 0 ] = 11 (table 1: positive traversing direction)
● MD18342 $MN_MM_CEC_MAX_POINTS[ 1 ] = 11 (table 2: negative traverse 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!
