Meaning
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
beginning 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
running in parallel, such as e.g. synchronized actions.
Note
The search speed depends on MD settings.
