Set the desired search variant in the "Search Mode" window.
The set mode is retained when the control is shut down. When you activate the "Search"
function after restarting the control, the current search mode is displayed in the title row.
With calculation
- without approach
In order to be able to approach a target position in any circumstance (e.g.
tool change position).
The end position of the target block or the next programmed position is
approached using the type of interpolation valid in the target block. Only the
axes programmed in the target block are moved.
:
If machine data 11450.1=1 is set, the rotary axes of the active swivel data
record are pre-positioned after the block search.
With calculation
- with approach
It is used to be able to approach the contour in any circumstance.
The end position of the block prior to the target block is found with <CYCLE
START>. The program runs in the same way as in normal program pro-
cessing.
:
In a ShopTurn program, the search is only performed on G code-blocks.
With calculation
- skip extcall
This is used to speed-up a search with calculation when using EXTCALL
programs: EXTCALL programs are not taken into account.
: Important information, e.g. modal functions, which are located in the
EXTCALL program, are not taken into account. In this case, after the
search target has been found, the program is not able to be executed. Such
information should be programmed in the main program.
Without calculation For a quick search in the main program.
Calculations will not be performed during the block search, i.e. the calcula-
tion is skipped up to the target block.
All settings required for execution have to be programmed from the target
block (e.g. feedrate, spindle speed, etc.).
With program test Multi-channel block search with calculation (SERUPRO).
All blocks are calculated during the block search. Absolutely no axis motion
is executed, however, all auxiliary functions are output.
The NC starts the selected program in the program test mode. If the NC
reaches the specified target block in the actual channel, it stops at the be-
ginning of the target block and deselects program test mode again. After
continuing the program with NC start (after REPOS motion) the auxiliary
functions of the target block are output.
For single-channel systems, the coordination is supported with events run-
ning in parallel, e.g. synchronized actions.
The search speed depends on MD settings.
