6.15.6 Input phase failure detection

: Input phase failure detection mode selection

• Function

This parameter detects inverter input Phase failure. If the abnormal voltage status of main circuit ca- pacitor persists for few minutes or more, the tripping function and the FL relay will be activated. At

the same time, the trip information will also displayed.

If the power capacity is larger than the inverter capacity (more than 200kVA or more than 10 times), detection errors may occur. If this actually happens, install an AC or DC reactor.

(Disabled) ...... No tripping (FL relay deactivated).

(Enabled)....... Phase failure detection is enabled during operation. The inverter will trip if the

abnormal voltage status of main circuit capacitor persists for ten minutes or more. (FL relay activated.)

6.15.7 Control mode for small current

: Small current trip selection

: Small current (trip/alarm) detection current

: Small current (trip/alarm) detection time

• Function
The	parameter allows the inverter to be tripped if a current smaller than the
	-specified value flows for more than the	-specified time. When tripping is se-
lected, enter the detection time to tripping. Trip information is displayed as “			”.
	(OFF)...... No tripping (FL relay deactivated).
	A small current alarm can be put out by setting the output terminal function selection
	parameter.
	(ON)........ The inverter is tripped (FL relay activated) only after a small current has been de-
	tected for more than the	-specified time during operation.
