Code
(hex)
Check for overloaded motorMotor current is too high.Motor overload7122
Adjust the parameters used for the
motor overload function.
(35.51…35.53, 35.55, 35.56)
Check connections and brake resist-
or dimensioning.
Brake resistor broken or
not connected.
Brake resistor7181
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings and fault limit
settings. Check braking cycle limits.
Brake resistor temperat-
ure has exceeded the lim-
it.
BR excess tem-
perature
7183
Check connections.Brake resistor short cir-
cuit or brake chopper
control fault.
Brake resistor
wiring
7184
Check the electrical specifications.
Replace brake chopper.
Short circuit in brake
chopper IGBT.
BC short circuit7191
Let chopper cool down. Check am-
bient temperature, cooling fan, air
flow, resistor overload protection
function settings, braking cycle
limits and supply voltage.
Brake chopper IGBT tem-
perature exceeded intern-
al fault limit.
BC IGBT excess
temp
7192
Check connections, brake settings
and brake acknowledgment signal.
Mechanical brake control
is faulty. Brake open ac-
knowledgment is not
matching the actual
status.
Mech brake
opening failed
71A3
Check the minimum/maximum
speed settings, parameters 30.11
Minimum speed and 30.12 Maxim-
um speed, motor braking torque,
torque control, brake chopper and
resistor(s).
Motor is turning faster
than highest allowed
speed.
Overspeed7310
Check predefined ramp times
(23.11…23.15 for mode Off1, 23.23
for mode Off3).
Emergency stop did not
finish within expected
time.
Emergency ramp
failed
73B0
Check the auxiliary code.Maximum allowed output
frequency exceeded.
