Fault messages

Code Fault
(hex)
2E00 Overcurrent
2E02 Short circuit
2E04 IGBT overload
2E05 BU current difference
2E08 External earth fault
2E0C User current fault
3E00 Input phase loss
Programmable fault:
131.21 Supply phase loss
3E04 DC link overvoltage
Cause
Too high inverter load or short
circuit.
DC/DC converter has detected
short circuit.
Excessive IGBT junction to
case temperature.
Phase current difference
between parallel-connected
modules.
External earth fault trigged by
input selected with parameter
131.28 Ext earth leakage
signal source.
Sum current of the three
phases has exceeded the limit
defined with parameter 131.25
User current fault limit.
Input phase loss detected by
the IGBT bridge.
Excessive intermediate circuit
DC voltage
Fault tracing 183
What to do
Check the load and busbars.
Check supply cable.
Check there are no power factor
correction capacitors or surge absorbers
in supply cable.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected modules,
"Y YY" specifies through which BCU
control unit channel the fault was
received. "ZZ" indicates the location of
the short circuit (0: No detailed
information available, 1: Upper branch of
U-phase, 2: Lower branch of U-phase,
4: Upper branch of V-phase, 8: Lower
branch of V-phase, 10: Upper branch of
W-phase, 20: Lower branch of W-phase,
other: combinations of the above).
After correcting the cause of the fault,
reboot the control unit (using parameter
196.08 Control board boot) or by cycling
power.
Check the load.
Check cable connections.
Check mains supply and fuses.
Check external earth fault source.
Usually only one device is allowed in the
same network.
Check the value of parameter
User current fault limit.
Check current limits of parameters
130.119 Minimum current
Maximum current.
Check that the DC bus voltage is not
dropping (against the energy storage
voltage) so that the current can flow
uncontrolled from the energy storage to
the DC bus via the freewheeling diodes.
Check the AC fuses.
Check for input power supply imbalance.
Check that parameter 195.01 Supply
voltage is set according to the supply
voltage in use.
With parallel-connected modules,
check the auxiliary code (format XXXY
YYZZ). "Y YY" specifies through which
BCU control unit channel the fault was
received.
