Enables/disables communication between the drive and
fieldbus adapter A, and specifies the slot the adapter is
installed into.
Communication between drive and fieldbus adapter A

comm loss t out.
No action taken.
Communication break detection active. Upon a
communication break, the drive trips on a
communication fault and coasts to a stop.
Communication break detection active. Upon a
communication break, the drive generates a warning
FBA A communication) and freezes the speed to the level the
drive was operating at. The speed is determined on the basis
of actual speed using 850 ms low-pass filtering.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Communication break detection active. Upon a
