Example
As an example of using the chart, we will modify a parameter while displaying it, starting from the
Top Level Menu referred to in the chart as the MAINMENU screen. This example assumes you
have read the previous sections of this manual. The example will concentrate more on the flow of
screens and how it relates to the chart, rather then the actual operations being performed by each
screen. The symbols refer to those of the chart. Descriptions of movement, ie. lateral, refer to
flow depicted on the chart.
Displaying the MAINMENU, press the [F4] key. The DISPLAY GROUP screen is now shown.
Cursor to a parameter group and press the [enter] key. This laterally moves us to the DISPLAY
screen. Since you selected a parameter group, pressing the [F7] key takes us into a selection
operation (symbol 'D') in which the SELECT screen is displayed. This allows us to use the cursor
keys to select the desired parameter.
Pressing the [enter] key laterally moves us to the symbol T which ends the selection process. For
this example, the symbol T laterally moves to the symbol M which defines a new process in which
the selected parameter can be modified. The MODIFY PARAMETER screen is now displayed.
To change the parameter, you must have the proper access to it. If required press the [F8] key to
display the ACCESS screen, as represented by the symbol P. Obtain the access from this screen
and press [F10] to exit. This will return you to the MODIFY PARAMETER screen. When you are
finished with this screen, press [F10] exit and you will be returned to the SELECT screen (via
symbols M and T). Pressing [F10] again will return you to the DISPLAY screen (via the symbol
D). Successive presses of the [F10] key will return you to the DISPLAY GROUP and finally to
either the MAINMENU or the MESSAGE screen.
If you have changed an data in the drive, the [F10] Exit key will bring up the MESSAGE screen.
The message will remind you that the changes made in the drive are only temporary, unless
saved to EEPROM. If you desire the data to be temporary, press [F9] 'No' and you will continue
onto the MAINMENU. If you press [F8] 'Yes', the EEPROM screen is entered, from which you can
save the data. Exiting the EEPROM screen returns you to the MAINMENU. Pressing the [F10]
Exit key on the MESSAGE screen will return you to the DISPLAY GROUP screen.
