Function: Activate block search
A channel is switched to search mode and the appropriate acknowledgement then transmitted.
The search is then executed immediately by the NC. The search pointer must already be in
the NC at this point in time. The search can be interrupted at any time by an NC RESET. Once
the search is successfully completed, the normal processing mode is reactivated automatically.
NC start then takes effect from the located search target.
It is the sole responsibility of the operator to ensure a collision-free approach path.
