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.
7310
Overspeed
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.
Check minimum/maximum speed
settings, parameters
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
73B0
Emergency ramp
failed
Emergency stop did not finish
within expected time.
Check the settings of parameters
Emergency ramp supervision delay
Check the predefined ramp times
(
for
mode Off3).
7510
FBA A communication
Programmable fault:
Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups
,
,
and
Check cable connections.
Check if communication master is able to
communicate.
8001
ULC underload fault
User load curve: Signal has
been too long under the
underload curve.
See parameter
.
8002
ULC overload fault
User load curve: Signal has
been too long over the
overload curve.
See parameter
.
80A0
AI supervision
Programmable fault:
An analog signal is outside the
limits specified for the analog
input.
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
