Troubleshooting
-239-
Fault
code
Fault type Possible cause Corrective measures
OH1
Overheat of rectifier
module
Air duct is blocked or fan is
damaged;
Ambient temperature is too
high;
Long-time overload running
Ventilate the air duct or
replace the fan;
Lower the ambient
temperature
OH2
Overheat of inverter
module
EF External fault
SI external fault input
terminal acts
Check external device input
CE
485 communication
fault
Baud rate is set improperly;
Communication line fault;
Communication address
error;
Communication suffers from
strong interference
Set proper baud rate;
Check the wiring of
communication interfaces;
Set proper communication
address;
Replace or change the wiring
to enhance anti-interference
capacity
ItE
Current detection
fault
Poor contact of the
connector of control board;
Hall component is
damaged;
Exception occurred to
amplification circuit
Check the connector and re-
plug.
Replace the hall component;
Replace the main control
board
tE
Motor autotuning
fault
Motor capacity does not
match with the inverter
capacity, this fault may
occur easily if the difference
between them is exceeds
five power classes;
Motor parameter is set
improperly;
The parameters gained
from autotuning deviate
sharply from the standard
parameters;
Autotuning timeout
Change the inverter model,
or adopt V/F mode for control;
Set proper motor type and
nameplate parameters;
Empty the motor load and
carry out autotuning again;
Check motor wiring and
parameter setup;
Check whether upper limit
frequency is larger than 2/3 of
the rated frequency
EEP EEPROM fault
R/W error occurred to the
control parameters;
EEPROM is damaged
Press STOP/RST to reset;
Replace the main control
board
PIDE
PID feedback offline
fault
PID feedback offline;
PID feedback source
disappears;
Check PID feedback signal
wires;
Check PID feedback source
bCE Brake unit fault
Brake circuit fault or brake
tube is damaged;
The resistance of external
brake resistor is too small
Check the brake unit, replace
with new brake tubes;
Increase brake resistance
END Running time is up
The actual running time of
the inverter is larger than
the set running time
Ask help from the supplier,
adjust the set running time
