function
Cause
Brake chopper IGBT
temperature has exceeded
internal fault limit.
Motor is turning faster than
highest allowed speed due to
incorrectly set
minimum/maximum speed,
insufficient braking torque or
changes in load when using
torque reference.
Emergency stop did not finish
within expected time.
Cyclical communication
between drive and fieldbus

adapter module A or between
PLC and fieldbus adapter
module A is lost.
User load curve: Signal has
been too long under the
underload curve.
User load curve: Signal has
been too long over the
overload curve.
An analog signal is outside the
limits specified for the analog
input.

What to do
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
Brake chopper).
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
Check minimum/maximum speed
settings, parameters 30.11 Minimum
speed and 30.12 Maximum
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
Check the settings of parameters
Emergency ramp supervision
Emergency ramp supervision
Check the predefined ramp times
(23.11...23.15 for mode Off1,
mode Off3).
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups
Fieldbus adapter (FBA),
settings, 52 FBA A data in
data out.
Check cable connections.
Check if communication master is able to
communicate.
See parameter 37.04 ULC underload
actions.
See parameter 37.03 ULC overload
actions.
Check signal level at the analog input.
Check the auxiliary code.
Check the wiring connected to the input.
Check the minimum and maximum limits
of the input in parameter group
