8. Trouble shooting
8.1 Fault and trouble shooting
The inverter has perfect functions to carry out effect protection; meanwhile the
performance of equipment can be full played. Please refer to the following table to
analyze the possible fault and find out the reason for exclusion. When the equipment is
damaged, please contact local agent, service center or manufacturers for the solution.
Fault Code
Fault Type
Reason
Solution
OUT1
IGBT Ph-U fault
1. Acc/Dec time is too
short.
2. IGBT module fault.
3. Malfunction caused by
interference.
4. Grounding is not
properly.
1. Increase Acc/Dec
time.
2. Ask for support.
3. Inspect external
equipment and eliminate
interference.
OUT2
IGBT Ph-V fault
OUT3
IGBT Ph-W fault
OC1
Over-current
when
acceleration
1. Acc time is too short.
2. Voltage is too low.
3. Power of the inverter is
too low.
1. Increase Acc time.
2.Check the input power
3. Select bigger capacity
inverter.
OC2
Over-current
when
deceleration
1. Dec time is too short.
2. Inertia torque of the load
is big.
3. Power of the inverter is
too low.
1. Increase Dec time.
2. Add proper braking
kits.
3. Select bigger capacity
inverter.
OC3
Over-current
when constant
speed running
1. The load transients or is
abnormal.
2.Voltage is too low
3. Power of the inverter is
too low.
4. The close loop runs at a
high speed or offline and
fault to the encoding disk.
1. Check the load and
reduce the transients.
2. Check the input
power.
3. Select bigger capacity
inverter.
4. Check the encoding
disk and wiring.
