Fault tracing 431
7100
Excitation current
Excitation current feedback
low or missing
Contact your local ABB representative.
7121
Motor stall
Programmable fault:
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Check motor load and drive ratings.
Check fault function parameters.
7122
Motor overload
Motor current is too high.
Check for overloaded motor
Adjust the parameters used for the motor
overload function. (

7181
Brake resistor
Brake resistor broken or not
connected.
Check that a brake resistor has been
connected.
Check the condition of the brake resistor.
Check the dimensioning of the brake
resistor.
7183
BR excess
temperature
Brake resistor temperature has
exceeded fault limit defined by
parameter
.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
).
Check fault limit setting, parameter
Check that braking cycle meets allowed
limits.
7184
Brake resistor wiring
Brake resistor short circuit or
brake chopper control fault.
Check brake chopper and brake resistor
connection.
Ensure brake resistor is not damaged.
7191
BC short circuit
Short circuit in brake chopper
IGBT.
Ensure brake resistor is connected and
not damaged.
Check the electrical specifications of the
brake resistor against chapter
Resistor
braking
in the
Hardware manual
of the
drive.
Replace brake chopper (if replaceable).
7192
BC IGBT excess
temperature
Brake 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 resistor overload protection
function settings (parameter group
).
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
71A3
Mech brake opening
failed
Mechanical brake control is
faulty. Brake open
acknowledgment is not
matching the actual status.
Check connections, brake settings and
brake acknowledgment signal.
