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.

Check if the connection of the
motor is normal or not
 Change the hoare

Change the main control panel
ETH2
Grounding
shortcut fault
2

The output of the inverter is
short circuited with the
ground.

There is fault in the current
detection circuit.
 Check if the connection of the
motor is normal or not
 Change the Hoare
Change the main control panel
dEu
Speed
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
Maladjustmen
t fault
 The control parameters of
the synchronous motors not
set properly.
 The autoturn parameter is
not right.
 The inverter 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.

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.
