Function
If a program requires more memory than the NC can provide for
execution, then it can be loaded continuously from the hard disk.

The "Program overview" opens.
The vertical softkey bar changes. Select the program you wish to
execute with the cursor (enable (x) must be set).
The highlighted program is loaded continuously to the NC working
memory during execution.
Press "NC Start".
The program remains stored on the hard disk while the "Execute from
hard disk" function is in progress.
The "External programs" window is opened.
The "Status" field indicates what percentage of the program has been
loaded from the hard disk.
Additional information
Programs which are executed from the hard disk are marked with
"EXT" in the program overview.
The identifier "EXT" does not disappear until a different part program
is selected in this channel.
When executing from the hard disk and with EXTCALL, only the 3-
