above). “ZZ” indicates the phase (1: U,
2: V, 3: W).
Check there are no power factor
correction capacitors or surge
absorbers in motor cable. Total earth leakage of inverter
modules is excessive. BU earth
leakage 2392
Measure insulation resistances of
motor cables and motor.
Contact your local ABB representative.
Check AC fuses. IGBT supply unit has detected an earth
fault. Earth leakage 2E01
Check for earth leakages.
Check supply cabling.
Check power modules.
Check there are no power factor
correction capacitors or surge
absorbers in supply cable.
If no earth fault can be detected,
contact your local ABB representative.
Check that the speed points of the
curve (defined by
29.70 Speed data
Parametrization of the speed/torque
limitation curve (in the DC voltage
reference chain) are inconsistent. Invalid
voltage chain
datapoints 3000
point 1…29.79 Torque data point 5)
are in increasing order.
Check input power line fuses. Intermediate circuit DC voltage is
oscillating due to missing input power
line phase or blown fuse. Supply phase
loss 3130
Check for loose power cable
connections.
Check for input power supply
imbalance.

1. The drive hardware is supplied
from a common DC bus.
2. Incorrect input power and motor

cable is connected to the motor
connection).
3. Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
3. Drive has detected load
unbalance typically due to earth
fault in motor or 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
99.4 Motor control
mode.)
Check that overvoltage control is on
(parameter
30.30 Overvoltage control ).
Excessive intermediate circuit DC
voltage. DC link
overvoltage 3210
Check that the supply voltage matches
the nominal input voltage of the drive.
Check the supply line for static or
transient overvoltage.
