DIN Programming
NC blocks start with the letter “N” followed by a block
number (with up to four digits).
Comments are enclosed in parentheses „[...]“. They are
located either at the end of an NC block or in a separate NC
block.
Instructions for operation
During editing, the CNC PILOT shows programmed contours
in a maximum of two simulation windows. You can select
the windows from the DIN PLUS main menu (Menu item
”Graphics—Windows”).
■
The starting point of the contour will be marked with a
”small box”
■
If the cursor is located on a block from ”blank or finished
part”, the corresponding contour element will be indicated in
red in the simulation window (”Contour display”)
• Additions/changes to the contour will only be
considered if the ”Graphics” menu item is
reactivated.
• Unambiguous NC block numbers are a prerequisite
for the contour display!
• For programming variables, see ”CNC PILOT 4290
User's Manual”
• For programming in the Y axis, see
”CNC PILOT 4290 with Y Axis User's Manual”
