520 Fault tracing
2330
Earth leakage
Programmable fault:
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
If the control unit is externally powered,
check the setting of parameter
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable.
Try running the motor in scalar control
mode if allowed. (See parameter
With parallel-connected modules, check
the auxiliary code (format XXXY YYZZ).
“Y YY” specifies through which BCU
control unit channel the fault was
received.
If no earth fault can be detected, contact
your local ABB representative.

Short circuit
Short-circuit in motor cable(s)
or motor
Check motor and motor cable for cabling
errors.
If the control unit is externally powered,
check the setting of parameter
Check that parameter
has been set correctly.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected inverter
modules, “Y YY” specifies through which
BCU control unit channel the fault was
received. “ZZ” indicates the location of
the short circuit (

After correcting the cause of the fault,
reboot the control unit (using parameter
) or by cycling
power.

IGBT overload
Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the motor cable.
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
