Fault tracing 521
2391
BU current difference
AC phase current difference
between parallel-connected
inverter modules is excessive.
Check motor cabling.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
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 (
1:
Channel 1,
2:
Channel 2,
4:
Channel 3,
8:
Channel 4, …,
800:
Channel 12,
other:
combinations of the above). “ZZ”
indicates the phase (
1:
U,
2:
V,
3:
W).
2392
BU earth leakage
Total earth leakage of inverter
modules is excessive.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Measure insulation resistances of motor
cables and motor.
Contact your local ABB representative.
3000
Invalid voltage chain
datapoints
Parametrization of the
speed/torque limitation curve
(in the DC voltage reference
chain) are inconsistent.
Check that the speed points of the curve
(defined by
) are in
increasing order.
3130
Input phase loss
Intermediate circuit DC voltage
is oscillating due to missing
input power line phase or
blown fuse.
Check input power line fuses.
Check for loose power cable
connections.
Check for input power supply imbalance.
3180
Charge relay lost
No acknowledgement received
from charge relay.
Contact your local ABB representative.
3181
Wiring or earth fault
Programmable fault:
The drive hardware is supplied
from a common DC bus.
Switch off the protection in parameter
Incorrect input power and
motor cable connection (i.e.
input power cable is connected
to the motor connection).
Check the power connections.
Check the input fuses.
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
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
.)
