Select Self-Diagnostic function in H60, Function group 2.

Define one terminal among P1toP8 terminals for this function.

To define P8 for this function, set t8 to “20”.

!

ATTENTION:Do not touch the inverter with hands 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 allows 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 options:

		0	Self-Diagnostic disabled
H601	Self-Diagnostic	1	IGBT fault and Ground fault2
	function	2	Output phase short & open circuit and Ground fault
		3	Ground fault (IGBT fault, Output phase short and open circuit)

1Selecting the higher number performs all functions within lower numbers.

2Ground fault of U phase in 2.2KW to 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

Once H60 is set to a specific value from 1 to 3 and the terminal defined for this function among P1 to P8 terminals is turned ON, the corresponding function is conducted, displaying “dIAG”

To stop this function, press STOP/RESET key on the keypad, turn the defined terminal OFF or turn the EST terminal ON.
