Selects the fieldbus reference FBA REF1 scaling and the actual value, which is sent to the fieldbus
(FBA ACT1).

50.05 FBA REF2 MODESEL
Selects the fieldbus reference FBA REF2 scaling.

Communication break detection active. Upon a communication break,
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.

No scaling (ie, 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.
Fieldbus adapter module uses torque reference scaling. Torque
reference scaling is defined by the used fieldbus profile (eg, with ABB
Drives Profile integer value 10000 corresponds to 100% torque
value). Signal 1.06 TORQUE
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 (eg, with ABB
Drives Profile integer value 20000 corresponds to the value of
parameter 25.02 SPEED

appropriate fieldbus adapter module.
One of the above selections is chosen automatically according to the
currently active control mode. See parameter group 34.
