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

program.

In "Teach In" mode, positions can be traversed and stored to
generate motion sequences which are then stored in the MDA
program.
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
other operating areas simply by pressing the "Machine area" key.
When you switch on the control, it is usually in the operating area
"Machine" in operating mode "Jog". (Please consult the machine
manufacturer's documentation!)
The state after power-up can be configured and might therefore
deviate from the default.
In operating mode "Jog" you can select the following machine
functions via the machine control panel or softkeys in the basic menu:
Inc (traverse in preset increments)
Repos (reposition at a defined position)
Ref (reference point approach to coordinate machine with the control
zero points)
In "MDA" mode, it is possible to select "Teach In" (storage of motion
sequences in a part program through position approach) by pressing
the MCP key.
