Function
The block search function allows you to run the part program forward
until you reach the block you require. Three types of search are
available:
1. With calculation on contour:
During block searches with calculation, the same calculations are
performed as in normal program mode. The complete destination
block is then executed analogously to normal program execution.
2. With calculation at block end point:
During block searches with calculation, the same calculations are
performed as in normal program mode. The interpolation mode
valid in the destination block is then applied to approach its end
point or the next programmed position.
3. Without calculation:
No calculations are performed during the block search.
The values stored in the control remain the same as they were
before the block search.
You can define the search destination
by direct positioning or
by specifying a block number, a label, a string, a program name
or any character string.
