Fault
code
Fault type Possible cause Solution
Incorrect motor parameter
settings.
The parameters gained
from autotuning deviate
sharply from the standard
parameters.
Autotuning timeout.
Check the motor wiring and
parameter settings.
Check whether the upper limit
frequency is larger than 2/3 of the
rated frequency.
EEP
EEPROM operation
fault
Control parameter
reading/writing error.
EEPROM 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
Braking circuit fault or
braking pipe damage.
Resistance of the external
braking resistor is small.
Check the braking unit, and
replace with a new braking pipe.
Increase the brake resistance.
END
Running time
reached
The actual running time of
the VFD is longer than the
internal set running time.
Ask for the supplier and adjust
the set running time.
OL3
Electronic overload
fault
The VFD reports overload
pre-alarm according to
the setting.
Check the load and the overload
pre-alarm points.
PCE
Keypad
communication fault
Keypad cable connected
improperly or
disconnected.
Keypad cable too long,
causing strong
interference.
Keypad or mainboard
communication circuit
error.
Check the keypad cable to
determine whether a fault occurs.
Check for and remove the
external interference source.
Replace the hardware and seek
maintenance services.
