Parameters and firmware blocks
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.
FW block:
Delay for fieldbus communication loss function.
FW block:
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
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
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

Fieldbus adapter module uses position reference scaling. Position
reference scaling is defined by parameters
