Editing part programs 
Overview 
A part program or sections of a part program can only be edited if currently not being executed. Any modifications to the part 
program are stored immediately. 
 
1.  Select the desired operating area. 
 
2.  Enter the program directory. 
 
 
3.  Select the program file you desire to edit. You can also search for a file or directory by either: 
●  Pressing the following softkey and specifying the desired criteria in the search dialog: 
 
 the file extension ".MPF" or ".SPF" must be entered if you desire to search for a program 
file. 
Or: 
●  Entering the first character on the main screen of the program directory. The system directly 
navigates to the first file starting with that character. 
 
4.  Press this key to open the program file. The system switches over to the program editor window. 
 
  5.  Edit the blocks in the window as required. Any program changes are automatically stored. See 
below for the detailed description of the editing options. 
 
6.  After finishing the editing, you can press this softkey to execute the program. The system switches 
to the "AUTO" mode in the machining area. 
 
With this softkey, the system automatically assigns block numbers to each block. The block 
numbers are inserted in front of each block in the ascending order in a step of 10.
