The address character of the word is usually a letter. The sequence of digits can contain a
sign and decimal point. The sign always appears between the address letter and the
sequence of digits. The positive sign (+) does not have to be specified.
Blocks and block format
An NC program consists of individual blocks. A block generally consists of (several) words.
A block should contain all the data required for performing an operation step and is
terminated with the character "L
F
" (LINE FEED = new line).
Note
The "L
F
" character does not have to be inserted manually, it is generated automatically when
you change lines.
Block length
A block can contain a maximum of 512 characters (including the comment and end-of-block
character "L
F
").
Note
Three blocks of up to 66 characters each are normally displayed in the current block display
on the screen. Comments are also displayed. Messages are displayed in a separate
message window.
