nd/background Edit]
"Background edit mode" and "Foreground edit mode" are available for the edit mode.
In the background edit mode
(1) The background edit mode is valid from after BG SRH is pressed to the BG END is pressed.
(2) “BACK GROUND EDITING” is displayed on the screen.
(3) Program indexing is carried out if INPUT key is pressed during the background editing.
(4) Program edit is valid while a program is executed if the program to edit is not running.
(5) Background edit mode will terminate if “COM.SRH” is operated from the edit screen during the
background edit.
(6) Background edit mode will not terminate if a program, which is not for the background edit, is externally
searched, search&start, or operation searched from other than edit screen during the background edit.
However, the background edit mode will terminate if it is the program for the background edit.
(Note) BG SRH cannot be operated for the program if it is the target for COM. SRH or in operation.
(The error message "E190 FORE EDITING" will be displayed.)
In the foreground edit mode
1) The foreground editing mode is a status where the program display during operation signal (Y72C) is
turned OFF, and the background editing mode is invalid.
2) When the system is not running (operation stopped), the edit cursor successively moves to the various
steps being executed in automatic operation.
3) Cursor movement is possible in the foreground editing mode, even in a write-protected status.
4) Machining programs in an operation stop status can be edited in single block mode.
5) The foreground editing mode is entered when the power is turned ON. If there is a program that is
already being operation searched, that program will become the foreground editing program.
6) Program indexing is carried out with a reset when not in operation.
(Note1) "EDIT POSSIBLE" is displayed on the screen when editing is possible, "EDIT IMPOSSIBLE" is
displayed when editing is not possible.
"EDIT IMPOSSIBLE" is displayed in the fixed cycle mode during feed hold or single block stop.
Other than edit mode in the foreground
When the program display during operation signal (Y72C) is turned ON, the program in operation is
displayed on the left side of the screen.
CAUTION
Resetting (search) the operation start position is operated when operation signal (Y72C) is turned
ON (terminate the foreground edit mode).
If the cursor for edit is placed at the head of the block, that block is the operation start position. If it
is placed at other than the head of the block, the head of the machining program is the operation
start position. Always make sure the operation start position before starting up automatically.
