Parameter assignment
Maximum path length
The maximum distance up to which a block is still compressed, is set using machine data:
MD20170 $MC_COMPRESS_BLOCK_PATH_LIMIT
Longer blocks are not compressed, but are traversed normally.
Recommended setting: 20 [mm]
Maximum deviation of the path feedrate FLIN and FCUB
The maximum permissible deviation of the path feedrate for active compressor function COMPON or
COMPCURV is specified in the machine data in conjunction with FLIN and FCUB:
MD20172 $MC_COMPRESS_VELO_TOL
The higher the permissible deviation, the more short blocks that can be compressed into a long block.
Recommended setting: 100 [mm/min]
Axial deviation
For each axis involved in the compression, a maximum tolerable deviation of the generated path from the
program points can be specified. The setting is done on an axis-for-axis basis using the machine data:
MD33100 $MA_COMPRESS_POS_TOL
The higher the permissible deviation, the more short blocks that can be compressed into a long block.
Recommended setting: 0.01 [mm]
Contour accuracy
The maximum tolerable deviation of the generated path from the programmed points is specified using the
following setting data for each channel:
SD42475 $SC_COMPRESS_CONTUR_TOL
Compression mode
The manner in which the maximum tolerable deviation from MD33100 and SD42475 is taken into account is set
via the units position in the machine data:
MD20482 $MC_COMPRESSOR_MODE (mode of compression)
Value
Meaning
xx0
The tolerances specified with MD33100 $MA_COMPRESS_POS_TOL are maintained
for all the axes (geo and orientation axes).
xx1
The tolerances specified with SD42475 $SC_COMPRESS_CONTUR_TOL are
maintained for the geometry axes.
The tolerances specified with MD33100 $MA_COMPRESS_POS_TOL are maintained
for the orientation axes.
