4.5 Correcting a program
As soon as a syntax error in the part program is detected by the controller, program
execution is interrupted and the syntax error is displayed in the alarm line.
Correction possibilities
Depending on the state of the control system, you can make the following corrections using
the Program editing function.
● Stop mode
Only program lines that have not yet been executed can be edited.
● Reset mode
All program lines can be edited.
Note
The "program correction" function is also available for execute from external; however,
when making program changes, the NC channel must be brought into the reset state.
Requirement
A program must be selected for execution in "AUTO" mode.
Procedure
1. The program to be corrected is in the Stop or Reset mode.
2. Press the "Prog. corr.” softkey
The program is opened in the editor.
The program preprocessing and the current block are displayed. The
current block is also updated in the running program, but not the
displayed program section, i.e. the current block moves out of the
displayed program section.
If a subprogram is executed, it is not opened automatically.
3. Make the necessary corrections.
4. Press the "NC Execute" softkey.
The system switches back to the "Machine" operating area and
selects "AUTO" mode.
5. Press the <CYCLE START> key to resume program execution.
