(19) Input phase loss
·
Turn on the power after you eliminate faults.
You may start fire.
·
You can change the setting for the function code E45 to 1* to change the detection sensitivity of the input
phase loss alarm. Change the parameter along with the application of the DC reactor (optional, standard
for 75 kW or more models).
You may damage your inverter if you set a wrong parameter.
(20) DB resistor overheating
NO
YES
NO
Change setting for function
code E45 to 1*
Tighten screws on
terminal block.
Connect wiring for all
three phases.
Input phase loss
Lin
Is wiring connected to all
main power supply
terminals
(L1/R, L2/S, L3/T)?
Are screws on terminal
block loose?
Is setting for function code
E45 changed to 1*?
Power supply is abnormal.
You must investigate power
supply system including
wiring.
YES
NO
YES
NO
Inverter fault or
malfunction due to
noise is suspected.
Contact FUJI.
Is imbalance rate in three-
phase power supply more
than 2%?
YES
NO
Install DC REACTOR
(optional, standard for 75 kW
or more models)
Is DC REACTOR used?
YES
YES
NO
YES
Related codes: E35 to E37
NO
Specify DB electronic
thermal relay functions
according to DB
specifications again.
Decrease repetition.
DB resistor overheating
dbH
You must review DB
resistor selection.
Does electronic thermal
relay characteristic match
DB characteristics?
Can you review braking
repetition?

Note: Power supply voltage imbalance rate [%] =
Maximum voltage [V] – Minimum voltage [V]
Three-phase average voltage [V]
