GD200A series VFD Fault tracking
-115-
Fault code Fault type Possible cause What to do
parameters autotuning and
the standard parameter is
huge

Autotune overtime

Check the motor connection
and set the parameter.

Check if the upper limit
frequency is above 2/3 of the
rated frequency.
EEP EEPROM 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 fault

PID feedback offline

PID feedback source
disappear

Check the PID feedback
signal

Check the PID feedback
source
bCE 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
ETH1
Grounding shortcut
fault 1

The output of the VFD is
short circuited with the
ground

There is fault in the current
detection circuit

The actual motor power
sharply differs from the VFD
power.

Check if the connection of
the motor is normal or not

Change the hall

Change the main control
panel

Set motor parameters
correctly.
ETH2
Grounding shortcut
fault 2
dEu
Velocity deviation
fault

The load is too heavy or
stalled

Check the load and ensure
it is normal

Increase the detection time

Check whether the control
parameters are normal
STo Maladjustment fault

The control parameters of
the synchronous motors not
set properly

The autotune parameter is
not right

The VFD is not connected
to the motor

Check the load and ensure
it is normal

Check whether the control
parameter is set properly or
not

Increase the maladjustment
detection time
END
Time reach of
factory setting

The actual running time of
the VFD is above the internal
setting running time

Ask for the supplier and
adjust the setting running
time
