Undoing
Procedure
(1) Select the program you want to restore to its previous state by
undoing.
(2) Place the program in the same editing status as that when the
editing operation was performed.
Example: To restore the program that was edited in the right
portion of the screen in MULTI EDIT mode
(simultaneous editing of two programs) in the
foreground, place the program in the right portion of
the screen in MULTI EDIT mode in the foreground.
(3) Press the [UNDO] soft key.
(4) Press the [EXEC] soft key.
The cursor returns to the point to which it was positioned when
the editing operation was performed.
(5) Press the [EXEC] soft key.
Execute UNDO to return the program to its previous state.
NOTE
1 If UNDO is stopped while an NC program is being
restored to its previous state with UNDO, the NC
program returns to the state existing before UNDO
was started. The stored editing operation is,
however, erased.
2 UNDO may fail if restoring a program to its previous
state would leave an extremely small amount of free
space in program memory.
3 UNDO may fail if the program security parameters or
DI signal differs from that when the editing operation
was performed.
