OH1 Diode Over Heat
OH2 IGBT Over Heat
1. Inverter instant over current
2. Short circuit between the three phases
or grounding short circuit
3. Ducting block up or fan damaged
4. Too high ambient temperature
5. Loose connection of control panel wire
or loose plug-in unit
6.
Auxiliary power supply failure,
under-driving-voltage.

connected
8. Control panel malfunction
1. Please see Over Current
Solution
2. Rewiring
3. Clean the ducting or replace the
fan.
4.
Reduce the ambient
temperature.
5. Inspect and re-connect
6. Ask for service.
7. Ask for service.
8. Ask for service.
EF External Failure
1. SI external failure input terminal
activated
1. Check external device input
CE Comm Failure
1. Baud rate improperly setup.
2. Miscommunication of applied serial
communication.
3. Long time interrupt of communication.
1. Properly set up the baud rate.
2. Press Button STOP/RST to
reset, and ask for service
3.
Inspect communication
interface wiring
ITE Curr Detect Fail
1. Poor connection of control panel
connector.
2. Auxiliary power-supply failure.
3. Hall sensor failure.
4. Amplifying circuit failure.
1. Inspect connector, re-plug in.
2. Ask for service.
3. Ask for service.
4. Ask for service.
TE Motor learn fail
1. Mismatch of motor and inverter.
2. Improper setup of motor rated
parameters.
3. Too big discrepancy of parameters
from autotune and standard parameters

2. Set up rated parameters
according to motor nameplate.
3. Make the motor no load to
re-identify the failure.
4. Inspect motor connection, set
up parameters
OPSE System Failure
1. Interference seriously leads to master
control board unable to function properly.
2. Ambient noise leads to master control
board malfunction.

add power supply filter at the
power supply side.
2. Press STOP/RST to reset, ask
for service.
EEP EEPROM failure
1. Control parameters misread-write.
2. EEPROM failure.
1. Press STOP/RST to reset, ask
for service.
2. Ask for service
PIDE PIDfeedback fail
1. PID feedback disconnected.
2. PID feedback disappears.
1. Inspect PID feedback signal
wire.
2. Examine PID feedback source.
BCE Brake unit fail
1. Braking circuit failure or brake tube
damaged.
2. Too low resistance of externally
connected braking resistor
1. Inspect braking unit, replace
braking tube.
2. Increase braking resistance.

7.2 common failures and solutions
Inverter may have following failures or malfunctions during operation, please refer to
following solutions to do simple analysis.
No display after power on
Use multimeter to examine whether or not the voltage of power supply is the same as
the inverter rated voltage. If the power supply has problem, examine it and eliminate
it.
Examine whether the three-phase rectification bridge is in good condition or not. If the
