Fault code Fault type Possible cause What to do
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 inverter
is short circuited with the
ground

There is fault in the current
detection circuit

The actual motor power
sharply differs from the
inverter power

Check if the connection of
the motor is normal or not

Change the hoare
 Change the main control
panel
 Set motor parameters
correctly
ETH2
Grounding
shortcut fault 2
 The output of the inverter
is short circuited with the
ground

There is fault in the current
detection circuit

The actual motor power
sharply differs from the
inverter power
 Check if the connection of
the motor is normal or not

Change the hoare

Change the main control
panel
 Set motor parameters
correctly
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
