UMI-B1 UL Series Inverter Keypad operation procedure25Stop parameters Running parameters Fault displayFigure 4-2 Displayed state4.3 Keypad operationOperate the inverter via operation panel. See the detailed structure description offunction codes in the brief diagram of function codes.4.3.1 How to modify the function codes of the inverterThe 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-levelmenu from the third-level menu. The difference is: pressing DATA/ENT will save the setparameters into the control panel, and then return to the second-level menu with shiftingto the next function code automatically; while pressing PRG/ESC will directly return tothe second-level menu without saving the parameters, and keep staying at the currentfunction code.Under the third-level menu, if the parameter has no flickering bit, it means the functioncode 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.Figure 4-3 Sketch map of modifying parameters
