Goodrive300-LIFT series inverter Fault tracking
-98-
Code Fault Possible cause Solution
broken

The amplifying circuit is
abnormal.

Change the main control
panel
tE
Motor-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 autotune
and
the standard
parameter is huge

Autotune overtime

Change the inverter mode

Set the rated parameter
according to the motor
name plate

Empty the motor load and
reindentify

Check the motor connection
and set the parameter.

Check if the upper limit
frequency is above 2/3 of
the rated frequency.
EEP
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
PID feedback
outline fault

PID feedback offline

PID feedback source
disappear

Check the PID feedback
signal

Check the PID feedback
source
bCE Brake unit fault

Braking circuit fault or
damage to the braking
pipes

The external brake
resistor is not sufficient

Check the brake unit and ,
change new braking pipe

Increase the brake resistor
END Running time arrival
The actual running time of
the inverter is above the
internal setting running
time.
Ask for the supplier and
adjust the setting running
time.
OL3 Electrical overload
The inverter will report
overload alarm according
to the set value.
Check the load and the
overload pre-alarm point.
PCE
Keypad
communication fault

The connection of the
keypad wires is not good
or broken.

Check the keypad wires
and ensure whether there is
mistake.
