Reason

Solution

OUT1

IGBT Ph-U

fault

1. IGBT module fault;
2. Malfunction caused by

interference;

3. Grounding is not properly

1. Ask for support;
2. Inspect external equipment and

eliminate interference

OUT2

IGBT Ph-V

fault

OUT3

IGBT Ph-W

fault

Over-current

1. Sudden change of pump;
2. Low input voltage;
3. The capacity of controller is

small

1. Inspect pump and reduce the

Change;

2. Check the power supply;
3. Select Select bigger capacity

controller

Over-voltage

1. High input voltage;
2. Regenerative energy from the

motor is too large

1. Check the power supply;
2. Avoid to restart the motor until it

stop running completely

P.OFF

DC bus

under-voltage

Low input voltage

Check the the power supply
(photovoltaic array voltage)

Motor

overload

1. Low input voltage;
2. Improper current protection

threshold of motor;

3. Sudden change of pump;
4. The capacity of motor is too

small

1. Check the power supply

(photovoltaic array voltage);

2. Set the rated current of motor

properly;

3. Check the pump, adjust the value

of torque boost;

4. Select proper capacity motor

SPO

Output phase

failure

Open-phase occurred at output
side of main circuit

Check the wiring, installation and
motor

Overheat fault

1. Sudden over-current;
2. Input/output side has short

circuit;

3. Cooling fans of controller

stopped or damaged,Obstruction
of ventilation channel;

4. Ambient temperature is too

high;Carrier frequency is too
high;Near heat source;

5. Wires or connectors of control

board are loose;

6. Auxiliary power supply unit is

damaged or low driving voltage
for IGBT;

1. Refer to measures of over-current;
2. Check the wiring;
3. Replace cooling fans;

Clear the ventilation channel;

4. Install cooling unit;

Decrease carrier frequency;
Remove the heat source;

5. Check the wires and connectors;
6. Ask supplier for support;
7. Ask supplier for support;
8. Ask supplier for support
