ShopTurn has automated this process. Any necessary tool change is automatically
executed with ShopTurn program steps with this block search variant.
Please observe the information provided by the machine manufacturer.
The function is only available if there is an interruption point. After a program interruption
(CYCLE STOP, RESET or power off), the controller saves the coordinates of the

A change of planes is only possible if an interruption point located in a subprogram is
selected. It is thus possible to switch to the main program level and back to the level of

You can search for a specific point in subprograms with the search pointer if there is no
interruption point.
Software option
You require the "Extended operator functions" option for the "Search pointer"
