Function
The Machine operating area includes all functions and influencing
variables which initiate actions on the machine tool or measure its
status.
There are three different modes in this area:
• JOG: JOG is the mode required for manual operation and
setting up of the machine. The setup functions provided are
"Reference point approach", "Repositioning", "Handwheel" or
"Traverse in preset increments" and "Redefine control zero"
(preset).
• 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 MDI
program.
• Automatic: Fully automatic operation
Part programs are executed fully automatically in Automatic mode,
i.e., part 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 "Machine"
operating area and in "JOG" mode.
Please consult the documentation provided by the machine
manufacturer!
