Possible Causes
Solutions
Power output phase loss
(reserved)
Lo
1: The cable connecting the AC drive and the
motor is faulty.
2: The AC drive’s three
-phase output is
unbalanced when the motor is running.
3: The drive board is faulty.
4: The module is faulty.
1: Eliminate external faults.
2: Check whether the motor three-
phase winding is normal.
3: Looking for technical support.
Module overheat
OH
1: The ambient temperature is too high.
2: The air filter is blocked.
3: The thermally sensitive resistor of the
module is damaged.
5: The inverter module is damaged.
1: Lower the ambient high
2: Clean the air filter.
3: Replace the damaged fan
4: Replace the damaged thermally
sensitive resistor.
5: Replace the inverter module.
External equipment fault
EF
1: External fault signal is input via X.
2: External fault signal is input via virtual I/O
Reset the operation.
Communication fault
CE
1: The host computer is in abnormal state.
2: The communication cable is faulty.
3: P028 is set improperly.
4: The communication parameters in group PD
are set improperly.
1: Check the cabling of host computer.
2: Check the communication cabling.
3: Set P028 correctly.
4: Set the communication parameters
properly.
Contactor fault
rAy
1: The drive board and power supply are
faulty.
2: The contactor is faulty.
1: Replace the faulty drive board or
power supply board.
2: Replace the faulty Contactor.
Current detection fault
IE
1: The HALL device is faulty.
2: The drive board is faulty.
1: Replace the faulty HALL device.
2: Replace the faulty
drive board.
Motor auto- tuning fault
TE
1: The motor parameters are not set according
to the nameplate.
2: The motor auto-tuning times out.
1: Set the motor parameters according
to the nameplate property.
2: Check the cable connecting the AC
drive and the motor.
EEPROM
read-writs fault
EEP
The EEPROM chip is damaged.
Replace the main control board.
AC drive hardware fault
OUOC
1: Overvoltage exists.
2: Overcurrent exists.
1: Handle based on overvoltage.
2: Handle based on
overcurrent.
Short circuit to ground
fault
GND
The motor is short circuited to the ground.
Replace the cable or motor.
Accumulative running
time reached
END1
The accumulative running time reaches the
setting value.
Clear the record through The parameter
initialization function.
Accumulative power-on
time reached
END2
The accumulative power- on time reaches the
setting value.
Clear the record through The parameter
initialization function.
Load becoming 0
LOAD
The AC drive running current is lower than
P9.64.
Check that the load is disconnected or
the setting of P9.64 and P9.65 is
correct.
PID feedback lost during
running fault
PIDE
The PIO feedback is lower than the setting of
PA.26.
Check the PID feedback signal or set
PA.26 to a proper value.
