Fig.4-3 Operation Process of Three-Level Menu
Caution: When operating on level 3 menu, press PRG key or ENTER key to
return to level-2 menu. The difference between ENTER and PRG keys is that
pressing ENTER KEY will save the setup parameter and return to level 2
menu and then automatically shift to the next function code, while pressing
PRG key will directly return to level 2 menu without saving the parameter,
and it will return to the current function code.
Take the modification of function code F0-05 from 10.00Hz to 15.00Hz as an
example. (The boldface bit indicates the flashing bit)
Fig.4-4 Example of Parameter Editing Operation
In level 3 menu, if the parameter has no flashing bit, it indicates that the
function code cannot be modified. The possible reasons include:
1) The function code is an unchangeable parameter, such as Such as actual
detection parameter, running record parameter, etc.
2) The function code cannot be modified in running status but can be
modified after the unit is stopped.
4.3 Viewing Method of Status Parameter
When the inverter is in stop or running status, multiple status parameters can
be displayed. It can select whether this parameter is to be displayed in binary
bit with the function codes F7-13 (running parameter) and F7-14 (stop
parameter). Refer to the descriptions of F7-13 and F7-14 in Chapter 6 for the
meanings of each bit.
In stop status, a total of 8 stop status parameters can be selected to display
or not to display, including setup frequency, bus voltage, DI input status, DO
output status, analog input AI 1 voltage, analog input AI2 voltage, actual
counting value, actual length value, the display of which can be switched by
pressing “NJ”key.
