534 Fault tracing
73B1 Stop failed Ramp stop did not finish within
expected time. Check the settings of parameters 31.37
Ramp stop supervision and 31.38 Ramp
stop supervision delay .
Check the predefined ramp times in
parameter group
23 Speed reference
ramp .
73F0 Overfrequency Maximum allowed output
frequency exceeded. Without a dual-use license, the fault limit
is 598 Hz. Contact your local ABB
representative for dual-use licensing
information.
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.
7520 FBA B communication
Programmable fault: 50.32
FBA B comm loss func
Cyclical communication
between drive and fieldbus
adapter module B or between
PLC and fieldbus adapter
module B is lost. Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter group
50
Fieldbus adapter (FBA) .
Check cable connections.
Check if communication master is able to
communicate.
7580 INU-LSU comm loss
Programmable fault: 60.79
INU-LSU comm loss
function
DDCS (fiber optic)
communication between
converters (for example, the
inverter unit and the supply
unit) is lost. Check status of other converter
(parameter group
06 Control and status
words ).
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.
7581 DDCS controller
comm loss
Programmable fault: 60.59
DDCS controller comm
loss function
DDCS (fiber optic)
communication between drive
and external controller is lost. Check status of controller. See user
documentation of controller.
Check settings of parameter group
60
DDCS communication .
Check cable connections. If necessary,
replace cables.
7582 MF comm loss
Programmable fault: 60.09
M/F comm loss function
Master/follower
communication is lost. See A7CB MF comm loss (page 513 ).
7583 Line side unit faulted The supply unit (or other
converter) connected to the
inverter unit has generated a
fault. The auxiliary code specifies the original
fault code in the supply unit control
program. See section
Auxiliary codes for
line-side converter faults (page 541 ).
