Fault code Fault type Possible cause Solutions
CE Communication error
1. The baud rate setting is
incorrect.
2. Fault occurs to the
communication wiring.
3. The communication address
is wrong.
4. There is strong interference to
the communication.
1. Set proper baud rate
2. Check the communication
connection distribution
3. Set proper communication
address.
4. Chang or replace the
connection distribution or
improve the anti-interference
capability.
ItE Current detection fault
1. The connection of the control
board is not good
2. Assistant power is bad
3. Hoare components is broken
4. The modifying circuit is
abnormal.
1. Check the connector and
repatch
2. Change the Hoare
3. Change the main control
panel
tE Autotuning fault
1. The motor capacity does not
comply with the inverter
capability
2. The rated parameter of the
motor does not set correctly.
3. The offset between the
parameters from autotune and
the standard parameter is huge
4. Autotune overtime
1. Change the inverter mode
2. Set the rated parameter
according to the motor name
plate
3. Empty the motor load.
4. Check the motor connection
and set the parameter.
5. Check if the upper limit
frequency is above 2/3 of the
rated frequency.
EEP EEPROM fault
1. Error of controlling the write
and read of the parameters
2. Damage to EEPROM
1. Press STOP/RST to reset
2. Change the main control
panel
PIDE PID feedback fault
1. PID feedback offline
2. PID feedback source
disappear
1. Check the PID feedback
signal
2. Check the PID feedback
source
bCE Braking unit fault
1. Braking circuit fault or
damage to the braking pipes
2. The external braking resistor
is not sufficient
1. Check the braking unit and ,
change new braking pipe
2. Increase the braking resistor
dEu Velocity deviation fault The load is too heavy or stalled.
1. Check the load and ensure it
is normal. Increase the detection
time.
2. Check whether the control
parameters are normal.
STo Maladjustment fault
1. The control parameters of the
synchronous motors not set
properly.
2. The autoturn parameter is not
right.
3. The inverter is not connected
to the motor.
1. Check the load and ensure it
is normal.
2. Check whether the control
parameter is set properly or not.
3. Increase the maladjustment
detection time.
END
Time reach of factory
setting
The actual running time of the
inverter is above the internal
setting running time.
Ask for the supplier and adjust
the setting running time.
PCE
Keypad
communication error
The keypad is not in good
connection or offline;
The keypad cable is too long
and there is strong interference;
Part of the communication
circuits of the keypad or main
board have fault.
Check the keypad cable and and
ensure it is normal;
Check the environment and
eliminate the interference
source;
Change hardware and ask for
maintenance service.
