3 KEYBOARD AND DISPLAY
The machine interface comprises a yellow Oled display (64 X 128) with black background and 5 buttons named
"MODE", "SET", "+", "-", "RUN/STOP" see Figure 9. The display shows the inverter values and statuses, and indicates
the functions of the various parameters. The button functions are summarised in Table 12.
When pressed for a longer interval, buttons +/- enable automatic increase/decrease of the selected parameter. If
button +/- is pressed for more than 3 seconds, the automatic increase/decrease speed is increased.
When the button + or – is pressed, the selected value is modified and saved immediately on the
permanent memory (EEprom). Unit shutdown in this phase, even if inadvertent, does not cause loss of the
set parameter.
The SET button is only used to exit the current menu and is not used to save any changes. Only in some
special cases described in 6 some values are implemented by pressing "SET" or "MODE".
You can leave any menu page and return to the main page in 2 ways:
by pressing the [SET] key
by timeout, once 5 min have passed since the last time a key was pressed.
3.1 Menus
The complete structure of all menus and relative items is shown in Table 14.
3.2 Access to menus
From all the menus you can access the other menus by a combination of keys.

pressed for at least 1 sec it enables the user to skip to the previous menu item.
The SET button enables the user to exit the current menu.
This decreases the current parameter (if modifiable).
This increases the current parameter (if modifiable).
