98 - 144 Fault Tracking
Fault
code
Fault type Possible cause What to do
CE
Communication
error
 The baud rate setting is incorrect
 Fault occurs to the communication
wiring.
 The communication address is
wrong
 There is strong interference to the
communication
 Set proper baud rate
 Check the communication
connection distribution
 Set proper communication address
 Change or replace the connection
distribution or improve the
anti-interference capability
ItE
Current detection
fault
 The connection of the control board
is not good
 Some board component is broken
 The keypad circuit is abnormal
 Check the connector and repatch
 Change the board
 Change the keypad
tE Autotuning fault
 The motor capacity does not comply
with the inverter capability
 The rated parameter of the motor
does not set correctly.

The offset between the parameters
from autotunting and the standard
parameters is huge
 Autotune overtime
 Change the inverter mode
 Set the rated parameter according to
the motor name plate
 Empty the motor load and reidentify

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 of controlling the write and
read of the parameters
 Damage to EEPROM
 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
 Check the PID feedback source
bCE Braking unit fault
 Braking circuit fault or damage to the
braking unit
 The external braking resistor is not
enough
 Check the braking unit
 Select proper braking resistor
ETH1
Grounding
shortcut fault 1
 The output of the inverter is short
circuited with the ground
 There is fault in the current detection
circuit
 The actual motor power sharply
differs from the inverter power.
 Check if the connection of the motor
is normal or not
 Change the board
 Change the main control panel
 Set motor parameters correctly
ETH2
Grounding
shortcut fault 2
dEu
Speed deviation
fault

The load is too heavy or stalled
 Check the load and ensure it is
normal

Increase the detection time

Check whether the control
parameters are normal
STo
Bad adjustment
fault
 The autotune parameter is not right
 The inverter is not connected to the
motor
 Check the load and ensure it is
normal
 Check whether the control
parameter is set properly or not
 Increase the bad adjustment
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
