Description
Settings for configuration of communication via a fieldbus
adapter.
Enables communication between the drive and fieldbus
adapter.
Communication between the drive and fieldbus adapter
disabled.
Communication between the drive and fieldbus adapter
enabled.
Selects how the drive reacts in a fieldbus communication
break. The time delay is defined by parameter
loss t out.
Communication break detection disabled.
Communication break detection active. Upon a
communication break, the drive trips on fault FIELDBUS
COMM and coasts to stop.
Communication break detection active. Upon a
communication break, the drive generates alarm FIELDBUS
COMM and sets the speed to the value defined by parameter
30.02 Speed ref safe.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Communication break detection active. The drive generates
alarm FIELDBUS COMM and freezes the speed to the level
the drive was operating at. The speed is determined by the
average speed over the previous 10 seconds.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Defines the time delay before the action defined by parameter
50.02 Comm loss func

Time delay.
Selects the fieldbus reference FBA REF1 scaling and the
actual value, which is sent to the fieldbus (FBA ACT1).
No scaling (i.e. data is transmitted without scaling). Source
for the actual value, which is sent to the fieldbus, is selected
by parameter 50.06 Fba act1 tr
Fieldbus adapter module uses torque reference scaling.
Torque reference scaling is defined by the used fieldbus
profile (e.g. with ABB Drives Profile integer value 10000
corresponds to 100% torque value). Signal
torque is sent to the fieldbus as an actual value. See the
User's Manual of the appropriate fieldbus adapter module.
Fieldbus adapter module uses speed reference scaling.
Speed reference scaling is defined by the used fieldbus
profile (e.g. with ABB Drives Profile integer value 20000
corresponds to parameter
01.01 Motor speed rpm
value. See the User's Manual of the appropriate fieldbus
adapter module.
