The TNC displays the following soft keys in the Program Run and
Test Run modes of operation:
View Soft key

3-D view
Limitations during program run
A graphical representation of a running program
is not possible if the microprocessor of the TNC
is already occupied with complicated machining
tasks or if large areas are being machined. Example:
Multipass milling over the entire blank form with
a large tool. The TNC interrupts the graphics and
displays the text
ERROR in the graphics window. The
machining process is continued, however.
In the test run graphics, the TNC does not depict
multi-axis operations during machining. The error
message
Axis cannot be shown appears in the
graphics window in such cases.
