①
Power supply remains in
≧
530V or
≦
300V.
②
One of phase is missing in power supply to inverter.
Possible
Causes
①
Power voltage remains more than upper limit (
≧
530V) or lower than lower limit (
≦
300V).
②
Check if there is broken wire (open) or phase missing in the power supply to inverter
(secondary side of circuit breaker).

①
Power supply check
Check if the power supply voltage is within
allowable range
(
300V
〜
530V).
②
Check if there is broken wire (open) in the

②
Inverter failure (detection part of motor lock
)
Trouble
Shooting
①
Check if fan motor for cooling is lock or faulty cable connection (disconnection or short circuit)
②
If there is no fault in motor and cable, it seems to be inverter board failure.
Replace inverter board.

Alarm
Logic
E5FF: Communication error between CPU board and inverter board during operation
Possible
Causes
①
Cable fault or connection error between inverter board and CPU board
②
Inverter board failure (Communication part to CPU board)
③
CPU board failure (Communication part to inverter board)
Trouble
Shooting
①
Disconnect the connector of cable between CPU board
(
connector X19A
)
and inverter board
(
connector X4A
)
and check pins visually.
Insert socket sucurely after checking of cable disconnection or short circuit.
②
If there is no connection error between both boards, it seems to be inverter board or CPU
board failure.

Action
Communication Interrupted
(

Restart after 3 minutes standby (permanent retry
)
(
"Communication Interrupted" is indicated on LCD and the E903 event log is recorded.)
