• If the target block is found, this block becomes the current block.HMI announces "Search target found" and displays the target block in the current block display.
• Action blocks (e.g., collection of auxiliary functions) are output after NC Start.
• Alarm 10208 is output to indicate that operator interventions such as Overstore or Mode Change after JOG are permissible.
• When you press NC Start, the program is started and the process resumes at this target block.
in the documentation are not related to block search without calculation, but is valid for all block search types. It is not clearly described. I passed this documentation problem to the STZ in Erlangen (documentation department).
The action blocks aren't definitely given out at NC-Start by using block search without calculation.

Here a better description:

Block search types

• Type 1: Block search without calculation
Block search without calculation is used to find a part program block in the quickest possible way. No calculation of any type is performed. The control status at the target block remains unchanged compared to the status before the start of the block search.
• Type 2: Block search with calculation at contour Block search with calculation at contour is used to enable the programmed contour to be approached in any situation. On NC Start, the start position of the target block or the end position of the block before the target block is approached. This is traversed up to the end position. Processing is true to contour.
• Type 4: Block search with calculation at block end point Block search with calculation at block end point is used to enable a target position (e.g.,tool change position) to be approached in any situation. The end position of the target block or the next programmed position is approached using the type of interpolation valid in the target block. This is not true to contour. Only the axes programmed in the target block are moved. If necessary, a collision-free initial situation must be created manually on the machine in "JOG REPOS" mode before the start of further automatic part program execution.
• Type 5: Block search with calculation in "Program test" (SERUPRO) mode SERUPRO (search run by programtest) is a cross-channel block search with calculation. Here, the NC starts the selected part program in "Program test" mode. On reaching the target block, the program test is automatically deselected. This type of block search also enables interactions between the channel in which the block search is being performed and synchronized actions as well as with other NC channels.

Nowis clear !
