Starting machining at a specific point
Use block search
If you would only like to perform a certain section of a program on the machine, then you
need not start the program from the beginning. You can also start the program from a
specified program block.
● Stopping or interrupting program execution
● Specify a target position, e.g. during remachining
Determining a search target
● User-friendly search target definition (search positions)
● Search pointer

– 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 subprogram)
The function is only available if there is an interruption point. After a program
interruption (CYCLE STOP or RESET), the controller saves the coordinates of the
– The search target is the higher program level of the interruption point (main program
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.
– Direct entry of the program path
Searching for point in subprogram
You can search for a specific point in subprograms with the search pointer if there is
no interruption point.
You require the "Extended operator functions" option for the "Search pointer"
function (only for 828D).
