4.3.4 Resume the execution of a program from the block where it was canceled.
After cancelling the execution of a program (error, reset, etc.) we usually want to resume the
execution from a particular block, usually a few blocks ahead the interruption block. To do
that, when cancelling the execution, the CNC saves and shows on the screen the block
number where the execution was cancelled (INT=####).
The way to proceed, once the execution is cancelled, is as follows.
1 In automatic mode, using the "EXBLK" softkey, execute the header blocks of the program
that set the machining conditions. See "4.4 Executing program blocks separately." on
page 87. The MDI/MDA mode allows changing the machining conditions at any time.
2 Once the machining conditions have been set, cancel the independent execution of
blocks ("EXBLK" softkey) and press the block selecting softkey to find and set the starting
block.
3 Select the text or line searching option. When the execution hs been cancelled with reset
or some error, the “Line” section of this window shows the line number where the
interruption took place. Press OK to place the cursor on that program line.
4 If necessary, move the cursor to select another line. The “Set beginning” option sets as
starting block for execution the block selected with the cursor.
5 Press [START] to begin executing from the selected block maintaining the history active
at the time.
Through block search, the CNC offers, , the most complete way to resume program execution after
interrupting (cancelling) the execution. Block search may be used to restore the program history up
to a particular block, reposition axes, go into tool inspection, etc. See "4.6 Block search." on page 93.
