4.2 Keypad operation

Operate the inverter via operation panel. See the detailed structure description of function
codes in the brief diagram of function codes.
4.2.1 How to modify the function codes of the inverter
The inverter has three levels menu, which are:
1. Group number of function code (first-level menu)
2. Tab of function code (second-level menu)
3. Set value of function code (third-level menu)
Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-level menu
from the third-level menu. The difference is: pressing DATA/ENT will save the set parameters
into the control panel, and then return to the second-level menu with shifting to the next
function code automatically; while pressing PRG/ESC will directly return to the second-level
menu without saving the parameters, and keep staying at the current function code.
Under the third-level menu, if the parameter has no flickering bit, it means the function code
cannot be modified. The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter,
operation records and so on;
2) This function code is not modifiable in running state, but modifiable in stop state.
Example: Set function code P00.01 from 0 to 1.
