3. KEYBOARD AND DISPLAY

The machine interface comprises a yellow Oled display (64 X 128) with black background and 4 buttons
named "MODE", "SET", "+",and "-"; 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 8.
The MODE button enables the user to move to the next items in the same menu. When
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).

Table 8: Button functions

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.
NOTE
:
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".
