0010 BC SHORT CIRCUIT
(0x7113)
Short circuit in brake chopper
IGBT
Replace brake chopper.
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
48.01…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
Br temp faultlim.
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:
30.08 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:
30.06 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:
30.04 Mot phase loss
Motor circuit fault due to
missing motor connection (all
three phases are not
connected).
Connect motor cable.
0017 ID-RUN FAULT
(0xFF84)
Motor ID Run is not completed
successfully.
Check motor settings (parameters
99.04…99.13).
Check that no limits prevent ID run. The
following must apply:
20.05 Maximum current >
99.06 Mot nom
current
For Reduced and Normal ID run:
– 20.01 Maximum speed > 55% of 99.09
Mot nom speed
– 20.02 Minimum speed <
0
– Supply voltage >
65% of 99.07 Mot
nom voltage
– Maximum torque (selected by 20.06
Torq lim sel) >
100% (only for Normal ID
run).
Retry.
