4.1 Data structure of the NC control
MDA: Semi-automatic operation
Part programs can be set up and processed block by block in
this mode. The tested blocks can then be stored in the part
In "Teach In" mode, positions can be traversed and stored to
generate motion sequences which are then stored in the MDA
Automatic: Fully automatic operation
Part programs are executed fully automatically in "Automatic"
mode, i.e. programs are selected, started, corrected, selectively
controlled (e.g. single block) and executed in Automatic.
You can switch to the "Machine" area at any time from any of the

Inc (traverse in preset increments)
Repos (reposition at a defined position)
Ref (reference point approach to coordinate machine with the control
In "MDA" mode, it is possible to select "Teach In" (storage of motion
