Table 13-2 Fault Messages (Alphabetical by Keypad Text)
Fault Fault # Cause What to do
Overspeed 7310 Motor is turning faster
than highest allowed
speed due to incorrectly
set minimum/maximum
speed, insufcient 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).
Line side converter
faulted
7358 The supply unit has
tripped on a fault.
If using a control panel or the Drive composer tool,
connect to the supply unit to read the fault code. Refer
to the rmware manual of the supply unit for instructions
related to the code.
Encoder internal 7380 Internal fault. Contact your local ABB representative.
Encoder 1 7381 Encoder feedback fault. See A7E1 Encoder 1.
Speed feedback
conguration
73A0 Speed feedback
conguration incorrect.
See A797 Speed feedback conguration.
Load position
feedback
73A1 No load feedback
received.
Check the event log for an auxiliary code (format XXYY
ZZZZ). “XX” species the number of the encoder interface
module (01: 91.11/91.12, 02: 91.13/91.14), “YY” species
the encoder (01: 92 Encoder 1 conguration, 02: 93
Encoder 2 conguration). “ZZZZ” indicates the problem
(see actions for each code below).
0001 Load gear denition
invalid or outside limits.
Check load gear settings (90.53 and 90.54).
0002 Feed constant denition
invalid or outside limits.
Check feed constant settings (90.63 and 90.64).
0003 Motor/load gear denition
invalid or outside limits.
Check motor/load gear settings (90.61 and 90.62).
0004 Encoder not congured. Check encoder settings (92 Encoder 1 conguration or 93
Encoder 2 conguration).
Use parameter 91.10 Encoder parameter refresh) to
validate any changes in the settings.
0005 Encoder stopped working. Check encoder status.
Emergency ramp
failed
73B0 Emergency stop did not
nish within expected
time.
Check the settings of parameters 31.32
Emergency ramp supervision and 31.33
Emergency ramp supervision delay.
Check the predened ramp times (23.11…23.19 for mode
Off1, 23.23 for mode Off3).
FBA A
communication
Programmable fault: 50.02
FBA A comm loss func
7510 Cyclical communication
between drive and
eldbus adapter module
A or between PLC and
eldbus adapter
module A is lost.
Check status of eldbus communication. See user
documentation of eldbus 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.
FBA B
communication
Programmable fault: 50.32
FBA B comm loss func
7520 Cyclical communication
between drive and
eldbus adapter module
B or between PLC and
eldbus adapter
module B is lost.
Check status of eldbus communication. See user
documentation of eldbus interface.
Check settings of parameter group 50 Fieldbus adapter
(FBA).
Check cable connections.
Check if communication master is able to communicate.
FA2FA DDCS com
loss
Programmable fault: 60.79
INU-LSU com loss ctrl
7580 DDCS (ber optic)
communication between
converters (for example,
the inverter unit and the
supply unit) is lost.
Check status of other converter (parameters 06.36 and
06.39).
Check settings of parameter group 60 DDCS
communication. Check the corresponding settings in the
control program of the other converter.
Check cable connections. If necessary, replace cables.
