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.

ULC underload fault
User load curve: Signal has been too
long under the underload curve.
See parameter 37.04 ULC underload
actions.
8002
ULC overload fault
User load curve: Signal has been too
long over the overload curve.
See parameter 37.03 ULC overload
actions.
