Fault Tracking 97 - 140
Fault code Fault type Possible cause What to do
ItE Current detection fault
1. The connection of the control
board is not good
2. Auxiliary power is bad
3. Some board component is
broken
4. The keypad circuit is
abnormal.
1. Check the connector and
repatch
2. Change the board
3. Change the keypad
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 parameters 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 and
reidentify
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 unit.
2. The external braking resistor
is not enough
1. Check the braking unit
2. Select proper braking resistor
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 wire is too long and
there is strong interference;
Part of the communication
circuits of the keypad or main
board have fault.
Check the keypad wire and
ensure it is normal;
Check the environment and
eliminate the interference
source;
Change hardware
