Fault
code
Fault type
Possible cause
Corrective measure
strong interference
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 VFD 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 VFD 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
Braking unit fault
Brake circuit fault or brake
tube is damaged;
The resistance of external
braking resistor is too small
Check the braking unit, replace
with new brake tubes;
Increase brake resistance
