38 Fault tracing
Code
(hex)
Fault Cause What to do
1010 Power module fault A general PM fault has
tripped
the drive. A more detailed
fault
message with indication of
which PM has a fault is
followed to this message.
Check the more detailed fault message
with the auxiliary code followed to this
fault message. The code indicates which
PM is affected.
2110 Trafo overcurrent The transformer primary
current has exceeded
internal
fault limit. Check the event log for an auxiliary code.
The code indicates the threshold which
has been exceeded:
0 - Transformer overcurrent
1 - Hardware overcurrent (95% of
maximum measurable current)
Check the primary cabling.
Check the transformer.
Contact your local ABB representative.
211B
Grid current
asymmetry
The difference between
measured transformer
primary
currents has exceeded
internal
fault limit.
Check the event log for an auxiliary code.
The code indicates which value has
exceed the threshold:
1 - Difference of phase A and B current
RMS values
2 - Difference of phase B and C current
RMS values
3 - Difference of phase C and A current
RMS values
Check for grid voltage asymmetry.
Check the fault limit settings (Contact
your local ABB representative).
2340 Short circuit
Short-circuit in motor
cable(s)
or motor.
Check motor and motor cable.
Check that there are no power factor
correction capacitors or surge absorbers
in motor cable.
3233
PM +5V power
supply
fault
The +5V power supply of a
PM
has failed.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Replace the faulty PM.
3236
PM DC link
capacitors
not balanced
The series connected
capacitors in the DC link of
a
PM are heavily
unbalanced.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Replace the faulty PM.
3239 PM diode open
circuit
PM rectifier's diode open
circuit is detected.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Replace the faulty PM.
