Su pplementary conditions
● The NC block compression is generally executed for linear blocks (G1).
● Only blocks that comply with a simple syntax are compressed:
N... G1X... Y... Z... F... ;comment
All other blocks are executed unchanged (no compression).
● Motion blocks with extended addresses such as C=100 or A=AC(100) are also condensed.
● The position values do not have to be programmed directly, but can also be indirectly specified using parameter
assignments, e.g. X=R1*(R2+R3).
● If the option "orientation transformation" is available, then NC blocks in which the tool orientation (and where relevant,
also the tool rotation) is programmed using direction vectors can also be compressed.
● It is interrupted by any other type of NC instruction, e.g., an auxiliary function output.
