Troubleshooting
-291-
Fault code
Fault type
Possible cause
Corrective measures
improperly;
The parameters gained
from autotuning deviate
sharply from the standard
parameters;
Autotuning timeout
parameter setup;
Check whether upper limit
frequency is larger than 2/3 of
the rated frequency
EEP
[21] EEPROM fault
R/W error occurred to the
control parameters;
EEPROM is damaged
Press STOP/RST to reset;
Replace the main control
board
PIDE
[22] PID feedback
offline fault
PID feedback offline;
PID feedback source
disappears;
Check PID feedback signal
wires;
Check PID feedback source
bCE
[23] Braking unit
fault
Braking circuit fault or
braking tube is damaged;
The resistance of external
braking resistor is too small
Check the braking unit,
replace with new braking
tubes;
Increase braking resistance
END
[24] Running time is
up
The actual running time of
the VFD is larger than the
set running time
Ask help from the supplier,
adjust the set running time
OL3
[25] Electronic
overload fault
The VFD releases overload
pre-alarm based on the set
value
Check the load and overload
pre-alarm threshold
PCE
[26] Keypad
communication fault
The keypad wire is poorly
contacted or disconnected;
The keypad wire is too long
and suffers strong
interference;
Circuit fault occurred to the
keypad or communication
part of the main board
Check the keypad wires to
confirm whether fault exists;
Check the surroundings to
rule out interference source;
Replace the hardware and
ask for maintenance service
UPE
[27] Parameter
upload error
The keypad wire is poorly
contacted or disconnected;
The keypad wire is too long
and suffers strong
interference;
Circuit fault occurred to the
keypad or communication
part of the main board
Check the surroundings to
rule out interference source;
Replace the hardware and
ask for maintenance service;
