182 Parameters
50
50 Fieldbus Settings for configuration of communication via a fieldbus
adapter.
50.01 Fba enable Enables communication between the drive and fieldbus
adapter.
Disable Communication between the drive and fieldbus adapter
disabled. 0
Enable Communication between the drive and fieldbus adapter
enabled. 1
50.02 Comm loss func Selects how the drive reacts in a fieldbus communication
break. The time delay is defined by parameter
50.03 Comm
loss t out .
No Communication break detection disabled. 0
Fault Communication break detection active. Upon a
communication break, the drive trips on fault FIELDBUS
COMM and coasts to stop. 1
Spd ref Safe 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.
2
Last speed 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.
3
50.03 Comm loss t out Defines the time delay before the action defined by parameter
50.02 Comm loss func is taken. Time count starts when the
link fails to update the message.
0.3 … 6553.5 s Time delay. 10 = 1 s
50.04 Fba ref1 modesel Selects the fieldbus reference FBA REF1 scaling and the
actual value, which is sent to the fieldbus (FBA ACT1).
Raw data 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 src .
0
Torque 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
01.06 Motor
torque is sent to the fieldbus as an actual value. See the
User’s Manual of the appropriate fieldbus adapter module.
1
Speed 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
19.01 Speed scaling value). Signal
01.01 Motor speed rpm is sent to the fieldbus as an actual
value. See the User’s Manual of the appropriate fieldbus
adapter module.
