Err51
The motor parameters are not
set based on the actual
situation.
Check that the motor
parameters are set
correctly and whether the
setting of rated current is
too small.

1: The cabling of the
temperature sensor becomes
loose.
2: The motor temperature is too
high.
1: Check the temperature
sensor cabling & eliminate
the cabling fault.
2: Lower the carrier
frequency or adopt other
heat radiation measures.

Fault
phenomenon
Possible Causes
1
There is no
display at
power-on.
2
“FZKJ” is
displayed at
power-on.
3
“Err23” is
displayed at
power-on.
4
The inverter
display is
normal upon
power-on.
But “FZKJ” is
displayed
after running
and stops
immediately.
5
Err14 (IGBT
overheat)
fault is
reported
frequently.
6
The motor
does not
rotate after
the inverter
runs.
1: There is no power supply to
the inverter or the power input
to the inverter is too low.
2: The power supply of the
switch on the driver board of the
inverter is faulty.
3: The rectifier bridge is
damaged.
4: The control board or the
operating panel is faulty.
5: The cable connecting the
control board and the driver
board and the operating panel
breaks.
1: Check the power supply.
2: Check the bus voltage.
3: Re-connect the 8-core
and 34-core cables.
4: Contact the agent or
company to support.
No.
Solutions
Fault
phenomenon
Possible Causes
1: The cable between the driver
board and the control board is
in poor contact.
2: Related components on the
control board are damaged.
3: The motor or the motor cable
is short circuited to the ground.
4: The HALL device is faulty.
5: The power input to the
inverter is too low.
1: Re-connect the 8-core
and 34-core cables.
2: Contact the agent or
company to support.
1: The motor or the motor
output cable is short-circuited
to the ground.
2: The inverter is damaged.
1: The cooling fan is damaged
or locked-rotor occurs.
2: The external control terminal
cable is short circuited.
1: The setting of carrier
frequency is too high.
2: The cooling fan is damaged,
or the air filter is blocked.
3: Components inside the AC
drive are damaged (thermal
coupler or others).
1: Measure the insulation
of the motor and the output
cable with a megger.
2: Contact the agent or
company to support.
1: Replace the damaged
fan.
2: Eliminate external fault.
1: Reduce the carrier
frequency (P0-15).
2: Replace the fan and
clean the air filter.
3: Contact the agent or
company to support.
1: Check the motor and the
motor cables.
2: The AC drive parameters are
set improperly (motor
parameters).
3: The cable between the driver
board and the control board is
in poor contact.
4: The driver board is faulty.
1: Ensure the cable
between the inverter and
the motor is normal.
2: Replace the motor or
clear mechanical faults.
3: Check and re-set motor
parameters.
