Compressing G0 blocks
The compression of G0 blocks is set for specific channels using the hundreds position in the machine data:
MD20482 $MC_COMPRESSOR_MODE (mode of compression)
A more detailed description of MD20482 can be found in:
References:
Function Manual Special Functions; Multi-Axis Transformations (F2),
Chapter: "Compression of the orientation"
Programming
The tolerance factor set using MD20560 $MC_G0_TOLERANCE_FACTOR can be temporarily overwritten by
programming
STOLF
in the part program:
Example:
The value in MD20560 is not changed by programming the tolerance factor. After a reset or end of part program,
the value set using MD20560 is effective again.
Value
Meaning
0xx
Circular blocks and G0 blocks are not compressed.
1xx
Circular blocks are compressed. Only COMPCAD.
2xx
G0 blocks are compressed.
See also MD20560 $MC_G0_TOLERANCE_FACTOR or NC command
STOLF
3xx
Circular blocks and G0 blocks are compressed.
