Program simulation and execution.
Block search.
With this option, it is possible, in a program or subroutine, to set the last block in order to
recover the program history and resume program execution from that point on with the same
conditions as if it were executed from the beginning. See "4.6 Block search." on page 93.
Automatic block search.
This option recovers the program history up to the block where the previous execution was
canceled. The CNC remembers the block where interruption was canceled, thus not being
necessary to set the stop block. If after the block search, the execution is resumed from that
point, it will do it in the same conditions as if it were executed from the beginning.
Manual block search.
This option recovers the program history up to a particular block of the program or of the
subroutine, set by the operator. If after the block search, the execution is resumed from that
point, it will do it in the same conditions as if it were executed from the beginning.
Find text.
This option shows a dialog box for placing the cursor on a particular line of the program or
search for text or a character string in the program.
Go to line.
In this area of the dialog box, the CNC requests the line number to go to. Key in the desired
number and press [ENTER], the cursor will then go to that line.
When selecting one of these options, the softkey menu shows the options available for setting
the search. To return to the main menu, press the [BACK] key.
• Number of blocks. With this option, it is possible to set the block search so it ends
n blocks before the block where the execution was interrupted.
If the number of blocks is ·0· (zero), the block search in the block
where the execution was interrupted.
• Simplified for CAM. This option is oriented to CAM programs. With this option, not
all the motion blocks are simulated; the CNC removes from the
simulation the blocks between the last block that changes the
motion conditions and the n-th block before the interruption
block.
• Interruption point. When pressing this softkey, the CNC finds the block where
block search will end. The last block will be the one where the
execution was interrupted; the "block number " softkey may be
used to set the block search to end n blocks before the one
where the execution was interrupted.
• First block. This option sets as starting block for block search the block
selected with the cursor. If the first block is not defined, the block
search starts at the first block of the program.
• Select subroutine. This option selects the stop condition in a global subroutine
which has been called upon from the program.
• Last block. This option sets as block search interruption block the block
selected with the cursor.
• Number of times. This option sets as stop condition, that the block selected as
the last block has been executed a specific number of times.
If a block containing a multiple machining cycle (·M· model) has
been selected as a stop block, the block search will end just
before the beginning of the nth modal cycle repeated in the
multiple machining.
• Interruption point. When pressing this softkey, the CNC finds the block where the
execution was interrupted and it selects it as stop block. This
block may be changed with the "Stop block" softkey.
• First block. This option sets as starting block for block search the block
selected with the cursor. If the first block is not defined, the block
search starts at the first block of the program.
