Logic
①Power supply voltage ≧AC530V or ≦AC300V.
②One of phase is open at power supply to inverter.
Possible
Causes
①Power supply voltage is too high (≧ AC 530V) or too low (≦ AC 300V).
② Check if there is broken wire (open) or open phase at the power supply for inverter
(secondary side of circuit breaker).
Trouble
Shooting
①Power supply check
Check if the power supply voltage is within
range （AC300V〜AC530V).
② Check if there is a broken wire (open)
between L1B, L2B and L3B (INV board) at
the secondary side of the circuit breaker.
① Provide the power supply voltage within
range.
Electrical parts may have damages.
② Repaire as needed

111 Communication Interrupted
（E5FF）
Alarm
Logic
E5FF: Communication error between CPU board and inverter board during operation
Possible
Causes
①Cable fault or connection error between inverter board and CPU board
②Inverter board failure (Communication part to CPU board)
③CPU board failure (Communication part to inverter board)
④Noise filter board failure
Trouble
Shooting
Step 1. Set the circuit breaker to ON (UNIT OFF), and then measure the voltage at the inverter
board (terminals L1B, L2B and L3B).
1.1 If there is no power voltage, check the power supply line including the noise filter board.
1.2 If there is power voltage but the LED (green) on the inverter board is not flashing,
replace the inverter board.
Step 2. Disconnect the connectors between the CPU board (connector X19A) and the inverter
board (connector X4A), and visually check the connector pins. After checking if any
cables are open or short circuited, securely insert the sockets.
Step 3. Replace the inverter board or CPU board.
Controller
Action
Communication Interrupted（E5FF） Restart after 3 minutes
（"Communication Interrupted" is displayed on LCD and E903 is recorded on trip report.
