overvoltage
Cause
Total earth leakage of inverter
modules is excessive.
IGBT supply unit has detected an earth
fault.
Parametrization of the speed/torque
limitation curve (in the DC voltage
reference chain) are inconsistent.
Intermediate circuit DC voltage is
oscillating due to missing input power
line phase or blown fuse.
No acknowledgement received from
charge relay.
1. The drive hardware is supplied
from a common DC bus.
2. Incorrect input power and motor
cable connection (i.e. input power
cable is connected to the motor
connection).
3. Drive has detected load
unbalance typically due to earth
fault in motor or motor cable.
Excessive intermediate circuit DC
voltage.

What to do
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.
Measure insulation resistances of
motor cables and motor.
Contact your local ABB representative.
Check AC fuses.
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
point 1 ... 29.79 Torque data point 5 )
are in increasing order.
Check input power line fuses.
Check for loose power cable
connections.
Check for input power supply
imbalance.
Contact your local ABB representative.
1. Switch off the protection in
parameter 31.23.
2. Check the power connections.
Check the input fuses.
3. 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 99.4 Motor control
mode .)
Check that overvoltage control is on
(parameter 30.30 Overvoltage
Check that the supply voltage matches
the nominal input voltage of the drive.
Check the supply line for static or
transient overvoltage.
