Cause
tripped
the drive. A more detailed
fault
message with indication of
which PM has a fault is
followed to this message.
The transformer primary
current has exceeded
internal
fault limit.
The difference between
measured transformer
primary
currents has exceeded
internal
fault limit.
Short-circuit in motor
cable(s)
or motor.
The +5V power supply of a
PM
has failed.
The series connected
capacitors in the DC link of
a
PM are heavily
unbalanced.
PM rectifier's diode open
circuit is detected.
What to do
Check the more detailed fault message
with the auxiliary code followed to this
fault message. The code indicates which
PM is affected.
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.
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).
Check motor and motor cable.
Check that there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Replace the faulty PM.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Replace the faulty PM.
Check the event log for an auxiliary code.
The code indicates which PM is affected.
Replace the faulty PM.
