Cause
Brake resistor temperature
has exceeded the limit.
Brake resistor short circuit
or brake chopper control
fault.
Short circuit in brake chop-
per IGBT.
Brake chopper IGBT temper-
ature exceeded internal
fault limit.
Mechanical brake control is
faulty. Brake open acknow-
ledgment is not matching
the actual status.
Motor is turning faster than
highest allowed speed.
Emergency stop did not fin-
ish within expected time.
Maximum allowed output
frequency exceeded.
Motor is turning faster than
the highest allowed fre-
quency due to incorrectly
set minimum/maximum fre-
quency or the motor rushes
because of too high supply
voltage or incorrect supply
voltage selection in paramet-
er 95.01 Supply voltage.
Diagnostics 147
What to do
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings and fault limit set-
tings. Check braking cycle limits.
Check connections.
Check the electrical specifications.
Replace brake chopper.
Let chopper cool down. Check ambi-
ent temperature, cooling fan, air flow,
resistor overload protection function
settings, braking cycle limits and sup-
ply voltage.
Check connections, brake settings
and brake acknowledgment signal.
Check the minimum/maximum speed
settings, parameters 30.11 Minimum
speed and 30.12 Maximum 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.
Check minimum/maximum frequency
settings, parameters 30.13 Minimum
frequency and 30.14 Maximum fre-
quency.
Check used supply voltage and
voltage selection parameter 95.01
Supply voltage.
