Meaning
This is used to speed-up a search with calculation when using EXTCALL
programs: EXTCALL programs are not taken into account.
Notice: 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 infor‐
mation should be programmed in the main program.
For a quick search in the main program.
Calculations will not be performed during the block search, i.e. the calculation
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.).
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 begin‐
ning of the target block and deselects program test mode again. After con‐
tinuing the program with NC start (after REPOS motion) the auxiliary func‐
tions of the target block are output.
For single-channel systems, the coordination is supported with events run‐
ning in parallel, e.g. synchronized actions.
Note
The search speed depends on MD settings.
