ABB ACQ80-04 User Manual

216 Fault tracing
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 30.11 Minimum
speed and 30.12 Maximum speed.
Check adequacy of motor braking torque.
Check applicability of torque control.
Check need for brake chopper and
resistor(s).
73F0 Overfrequency Maximum allowed output
frequency exceeded.
Check the auxiliary code.
00FA Motor is turning faster than the
highest allowed frequency due
to incorrectly set
minimum/maximum frequency
or the motor rushes because of
too high supply voltage or
incorrect supply voltage
selection in parameter 95.01
Supply voltage.
Check minimum/maximum frequency
settings, parameters 30.13 Minimum
frequency and 30.14 Maximum
frequency.
Check used supply voltage and voltage
selection parameter 95.01 Supply
voltage.
Other - Contact your local ABB representative,
quoting the auxiliary code.
7510 FBA A communication
Programmable fault: 50.02
FBA A comm loss func
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 50
Fieldbus adapter (FBA), 51 FBA A
settings, 52 FBA A data in and 53 FBA A
data out.
Check cable connections.
Check if communication master is able to
communicate.
8000 Unicos system error System fault. Power cycle.
8009 Current limit Motor actual current exceeded
the limit defined in parameter
30.17 Maximum current.
Reduce the motor load. Check for any
jam or stall in motor.
See parameter 30.17 Maximum current.
80A0 AI supervision
Programmable fault:
12.03 AI supervision
function
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 12
Standard AI.
80B0 Signal supervision 1
(Editable message text)
Programmable fault:
32.06 Supervision 1 action
Fault generated by the signal
supervision function 1.
Check the source of the fault (parameter
32.07 Supervision 1 signal).
80B1 Signal supervision 2
(Editable message text)
Programmable fault:
32.16 Supervision 2 action
Fault generated by the signal
supervision function 2.
Check the source of the fault (parameter
32.17 Supervision 2 signal).
