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)
Brake resistor short circuit or
brake chopper control fault.
Check brake chopper and brake resistor
connection.
Ensure brake resistor is not damaged.
0010 BC SHORT CIRCUIT
(0x7113)
Short circuit in brake chopper
IGBT.
Ensure brake resistor is connected and not
damaged.
0011 BC OVERHEAT
(0x7181)
Brake chopper IGBT
temperature has exceeded
internal fault limit.
Let chopper cool down.
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.
0012 BR OVERHEAT
(0x7112)
Brake resistor temperature has
exceeded fault limit defined by
parameter 48.06 BR TEMP
FAULTLIM.
Stop drive. Let resistor cool down.
Check resistor overload protection function
settings, parameters 48.01…48.05.
Check fault limit setting, parameter 48.06.
Check that braking cycle meets allowed
limits.
0013 CURR MEAS GAIN
(0x3183)
Difference between output
phase U2 and W2 current
measurement gain is too great.
Contact your local ABB representative.
0014 CABLE CROSS CON
(0x3181)
Programmable fault: 46.08
CROSS CONNECTION
Incorrect input power and motor
cable connection (i.e. input
power cable is connected to
drive motor connection).
Check input power connections.
0015 SUPPLY PHASE
(0x3130)
Programmable fault: 46.06
SUPPL PHS LOSS
Intermediate circuit DC voltage
is oscillating due to missing
input power line phase or blown
fuse.
Check input power line fuses.
Check for input power supply imbalance.
0016 MOTOR PHASE
(0x3182)
Programmable fault: 46.04
MOT PHASE LOSS
Motor circuit fault due to
missing motor connection (all
three phases are not
connected).
Connect motor cable.
