•
Blocks can no longer be stopped if they have been preprocessed in the buffer memory but not yet
executed without the "Decoding single block" being present.
•
A "Decoding single block" can be modified by "Overstore".
Note
With some functions (e.g. contour definition, tool radius compensation, soft
approach to contour) additional blocks are inserted by the control. Depending
on the number of insertions, the NC START key may have to be pressed
several times.
