4.3 Operation procedure

You can operate the inverter by using the keypad. For details about function code
descriptions, see the function code list.

4.3.1 Modifying function codes

The inverter provides three levels of menus, including:
1. Function code group number (level-1 menu)
2. Function code number (level-2 menu)
3. Function code setting (level-3 menu)
Note: When performing operations on the level-3 menu, you can press the PRG/ESC or
DATA/ENT key to return to the level-2 menu. If you press the DATA/ENT key, the set
value of the parameter is saved to the control board first, and then the level-2 menu is
returned, displaying the next function code. If you press the PRG/ESC key, the level-2
menu is returned directly, without saving the set value of the parameter, and the current
function code is displayed.
If you enter the level-3 menu but the parameter does not have a digit blinking, the
parameter cannot be modified due to either of the following reasons:
• It is read only. Read-only parameters include actual detection parameters and running
record parameters.
• It cannot be modified in running state and can be modified only in stopped state.
