0005 DC UNDERVOLTAGE
(0x3220)
Intermediate circuit DC voltage
is not sufficient due to missing
mains phase, blown fuse or
rectifier bridge internal fault.
Check mains supply and fuses.
0006 EARTH FAULT
(0x2330)
Programmable fault: 46.05
EARTH FAULT
Drive has detected load
unbalance typically due to earth
fault in motor or motor cable.
Check that there are no power factor
correction capacitors or surge absorbers in
motor cable.
Check that there is no earth fault in 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
(0xFF83)
Fan is not able to rotate freely or
fan is disconnected. Fan
operation is monitored by
measuring fan current.
Check fan operation and connection.
0008 IGBT OVERTEMP
(0x7184)
Drive temperature based on
thermal model has exceeded
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
(0x7111)
Braking resistor is missing,
damaged or there is a problem
in the resistor cabling.
Short circuit in the braking
chopper IGBT.
Ensure that the braking resistor is connected
and not damaged.
Replace the braking chopper.
0010 BC SHORT CIRCUIT
(0x7113)
Short circuit in the braking
chopper IGBT.
Ensure that the braking resistor is connected
and not damaged.
Replace the braking chopper.
0011 BC OVERHEAT
(0x7181)
Braking chopper IGBT
temperature has exceeded
internal fault limit.
Let 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 48.03…48.05.
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
