Cause
Fault in external device 2.
Fault in external device 3.
Fault in external device 4.
Fault in external device 5.
Current offset and gain measurement
calibration will occur at next start.
Drive has detected load unbalance
typically due to earth fault in motor or
motor cable.
Short-circuit in motor cable(s) or
motor.
Excessive IGBT junction to case
temperature. This warning protects
the IGBT(s) and can be activated by a
short circuit in the motor cable.
Intermediate circuit DC voltage too
high (when the drive is stopped).
Intermediate circuit DC voltage too
low (when the drive is stopped).

What to do
Check the external device.
Check setting of parameter
External event 2 source.
Check the external device.
Check setting of parameter
External event 3 source.
Check the external device.
Check setting of parameter
External event 4 source.
Check the external device.
Check setting of parameter
External event 5 source.
Informative warning. (See parameter
99.13 ID run requested.)
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 .)
If no earth fault can be detected,
contact your local ABB representative.
Check motor and motor cable for
cabling errors.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check the supply voltage setting
(parameter 95.1 Supply
that the wrong setting of the
parameter may cause the motor to
rush uncontrollably, or may overload
the brake chopper or resistor.
Check the supply voltage.
If the problem persists, contact your
local ABB representative.
Check the supply voltage setting
(parameter 95.1 Supply
that the wrong setting of the
parameter may cause the motor to
rush uncontrollably, or may overload
the brake chopper or resistor.
