(hex)
3E06 BU DC link difference
3E0B Output phase loss
3E11 ES voltage difference
3E12 ES overvoltage
3E13 ES undervoltage
4E02 IGBT temperature
4E03 Excess temperature
Cause
Difference in DC voltages
between parallel-connected
DC/DC converter modules.
Output circuit fault due to
missing output connection (all
the phases are not connected).
Measured and estimated
energy storage voltages differ
from each other more than
allowed (estimated voltage
being higher).
Measured or estimated energy
storage voltage has exceeded
the fault limit.
Measured or estimated energy
storage voltage is not
sufficient.
IGBT temperature is
excessive.
DC/DC converter module heat
sink temperature is excessive
due to eg, module overload,
fan failure or heatsink sensor.
(Control program generates
first a warning, then a fault.)
What to do
Check the DC fuses.
Check the connection to the DC bus.
If the problem persists, contact your local
ABB representative.
Check the auxiliary code (format XXXY
YYZZ). "XXX" specifies the source of the
first error (see "YYY"). "YYY" specifies
the module through which BCU control
unit channel the fault was received
(0: Channel 1, 1: Channel 2,
2: Channel 3, 4: Channel 4, 8: Channel 5,
..., 400: Channel 12).
Connect output cable.
Check parameter 131.24 ES voltage
difference.
Check the energy storage voltage
measurement circuit (if connected).
Use value 0 when the measurement is
not available.
Check parameter 131.23 ES over voltage
level.
Check parameters 130.113 Minimum ES
voltage and 130.114 Maximum ES
voltage.
Check the energy storage voltage
measurement circuit (if connected).
Check parameter 197.14 ES voltage
source. Use selection Zero
measurement is not available.
Check parameter 131.22 ES under
voltage level.
Check parameters 130.113 Minimum ES
voltage and 130.114 Maximum ES
voltage.
Check the energy storage voltage
measurement circuit (if connected).
Check parameter 197.14 ES voltage
source. Use selection Zero
measurement is not available.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against DC/DC
converter power.
