
Select Self-Diagnostic function in H60, Function group 2.

Define one terminal among P1~P8 terminals for this function.

To define P8 for this function, set I24 to “20”.
CAUTION:
Take caution not to touch the inverter by hand or other objects while performing this
function because current is flowing to the inverter output.

Perform Self-diagnostic function after input/output wiring of the inverter is finished.

This function enables the user to safely check for the IGBT fault, output phase open and
short, and Ground fault without disconnecting the inverter wiring.

There are 4 ways to select.

function
0 Self-Diagnostic disabled
1 IGBT fault and Ground fault
2)
2 Output phase short & open circuit and
Ground fault
3 Ground fault (IGBT fault, Output
phase short and open circuit)
1) Selecting the higher number performs the lower number’s function.
2) Ground fault of U phase in 2.2KW ~ 4.0KW inverters and ground fault of V phase in other
rating inverters may not be detected when selecting “1”. Select 3 to make sure to detect all
phase of U, V, W.

When setting H60 to a specific value from 1 to 3 and turn the terminal defined for this
function among P1 ~ P8 terminals ON, the corresponding function is conducted, displaying
“dIAG” and the previous menu will be displayed when this function is completed.

To stop this function, press STOP/RESET key on the keypad, turn the defined terminal OFF
or turn the EST terminal ON.
