GD310-UL series VFD Fault tracking
-175-
Fault
code
Fault type Cause Solution
tE
[20] Motor
autotuning fault

The motor capacity does
not comply with the VFD
capability

The rated parameter of the
motor does not set correctly.

The offset between the
parameters from autotune
and the standard parameter
is huge

Autotune overtime

Change the VFD mode

Set the rated parameter
according to the motor name
plate

Empty the motor load and
re-identify

Check the motor connection and
set the parameter.

Check if the upper limit frequency
is above 2/3 of the rated
frequency.
EEP
[21] EEPROM
operation 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
[22] PID
feedback offline
fault

PID feedback offline

PID feedback source
disappear

Check the PID feedback signal

Check the PID feedback source
bCE
[23] Braking
unit fault

Braking circuit fault or
damage to the braking
pipes

The external braking
resistor is not sufficient

Check the braking unit and,
change new braking pipe

Increase the braking resistor
END
[24] Running
time reached

The actual running time of
the VFD is above the
internal setting running
time.

Ask for the supplier and adjust
the setting running time.
OL3
[25] Electronic
overload

The VFD will report
overload pre-alarm
according to the set value.

Check the load and the overload
pre-alarm point.
PCE
[26] Keypad
communication
fault

The connection of the
keypad wires is not good or
broken.

The keypad wire is too long
and affected by strong
interference.

There is circuit fault on the
communication of the
keypad and main board.

Check the keypad wires and
ensure whether there is mistake.

Check the environment and avoid
the interference source.

Change the hardware and ask for
service.
