During program run it is possible to switch over to the
PROGRAMMING AND EDITING mode and enter a new program or
edit an existing one while the program being executed continues in
the background.

Operating time

The TNC displays the calculated machining time between the program
blocks and the status display. The TNC resets the counter for the
machining time when you select a new program.

Changing the erosion parameters during
program run

The TNC displays the erosion parameters of the current power stage
in a line on the screen. You can select the individual erosion
parameters with the horizontal arrow keys. Then use the vertical arrow
keys to change the parameters settings while the program is being
executed. Parameter settings that are changed during program run
will not be entered in the erosion table.

The machine tool builder can inhibit changing of specific
