Fault
code
Fault type
Possible cause
Solutions
ItE
Current
detection fault
The connection of the control
board is not good;
Assistant power is bad;
Hall components is broken;
The magnifying circuit is
abnormal
Check the connector and plug
wire again;
Change the hall;
Change the main control panel
tE
Autotuning fault
The motor capacity does not
match with VFD capacity;
The rated parameter of the
motor is set improperly;
The deviation between the
parameters from autotune and
the standard parameter is huge;
Autotune overtime
Change the VFD model;
Set the rated parameter
according to the motor
nameplate;
Empty the motor load;
Check the motor connection
and set the parameter;
Check if the upper limit
frequency is above 2/3 of the
rated frequency.
EEP
EEPROM fault
Error occurred to R/W of the
control parameter;
EEPROM is damaged
Press STOP/RST to reset;
Change the main control panel
PIDE
PID feedback
fault
PID feedback offline;
PID feedback source disappear
Check the PID feedback signal
wire;
Check the PID feedback source
bCE
Brake unit fault
Braking circuit fault or damage
to the brake pipes;
The external brake resistor is
not sufficient
Check the brake unit and
change to new brake pipe;
Increase the brake resistor
END
Time reach of
factory setting
The actual running time of the
VFD is larger than 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
ensure it is normal;
