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
