Block search
5.1 Selecting the function "Block search"
By pressing the HSK 1.5 "Block search" the block
search window opens as shown below.
If you would only like to perform a certain section of a program on the ma-
chine, then you don't have to start the program from the beginning. You
can also start the program from a specified program block.
Applications of this function are to stop or interrupt program execution and
to specify a target position (e.g. during machining).
Determination of search targets per:
a. Comfortable search target definitions (search positions)
Direct specification of the search target by positioning the cursor in the
selected program (main program).
Search target via text search.
The search target is the interruption point (main program and subpro-
gram). The function is only available if there is an interruption point. Af-
ter a program interruption ("CYCLE STOP" or "RESET"), the controller
saves the coordinates of the interruption point.
The search target is the higher program level of the interruption point
(main program and subprogram). The level can only be changed if it
was previously possible to select an interruption point in a subprogram.
It is then possible to change the program level up to the main program
level and back to the level of the interruption point.
