0006
EARTH FAULT
Programmable
fault: 46.03 EARTH
FAULT
Drive has detected load
unbalance typically due to
an earth fault in the motor
or motor cable.
Check that there are no power
factor correction capacitors or
surge absorbers in the motor cable.
Check that there is no earth fault in
the motor or motor cables:
measure insulation resistances of
motor and motor cable.
If no earth fault can be detected,
contact your local ABB
representative.
0007
FAN FAULT Fan is not able to rotate
freely or the fan is
disconnected. Fan
operation is monitored by
measuring the fan current.
Check the fan operation and
connection.
0008
IGBT OVERTEMP Drive temperature based
on the thermal model has
exceeded the internal fault
limit.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-
up.
Check motor power against unit
power.
0009
BC WIRING Brake resistor short circuit
or brake chopper control
fault.
Check brake chopper and brake
resistor connection.
Ensure that the brake resistor is not
damaged.
0010
BC SHORT
CIRCUIT
Short circuit in brake
chopper IGBT.
Ensure that the brake resistor is
connected and not damaged.
0011
BC OVERHEAT Brake chopper IGBT
temperature has exceeded
the internal fault limit.
Let the chopper cool down.
Check for excessive ambient
temperature.
Check for cooling fan failure.
Check for obstructions in the air
flow.
Check the dimensioning and
cooling of the cabinet.
Check resistor overload protection
function settings, parameters
48.02…48.04.
Check that the braking cycle meets
allowed limits.
Check that the drive supply AC
voltage is not excessive.
