Cause
Motor current is too high.
Brake resistor broken or
not connected.
Brake resistor temperat-
ure has exceeded the lim-
it.
Brake resistor short cir-
cuit or brake chopper
control fault.
Short circuit in brake
chopper IGBT.
Brake chopper IGBT tem-
perature exceeded intern-
al fault limit.
Mechanical brake control
is faulty. Brake open ac-
knowledgment is not
matching the actual
status.
Motor is turning faster
than highest allowed
speed.
Emergency stop did not
finish within expected
time.
Maximum allowed output
frequency exceeded.
What to do
Check for overloaded motor
Adjust the parameters used for the
motor overload function.
(35.51...35.53, 35.55, 35.56)
Check connections and brake resist-
or dimensioning.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings and fault limit
settings. Check braking cycle limits.
Check connections.
Check the electrical specifications.
Replace brake chopper.
Let chopper cool down. Check am-
bient temperature, cooling fan, air
flow, resistor overload protection
function settings, braking cycle
limits and supply voltage.
Check connections, brake settings
and brake acknowledgment signal.
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).
Check predefined ramp times
(23.11...23.15 for mode Off1, 23.23
for mode Off3).
Check the auxiliary code.
