Supplementary conditions
● The NC block compression is generally executed for linear blocks (
● Only blocks that comply with a simple syntax are compressed:
● Motion blocks with extended addresses such as
● The position values do not have to be programmed directly, but can also be indirectly
● If the option "orientation transformation" is available, then NC blocks in which the tool
● It is interrupted by any other type of NC instruction, e.g., an auxiliary function output.
