Drive trips on 7510 FBA A communication. This only occurs
if control is expected from the FBA A interface (FBA A
Fault
selected as source of start/stop/reference in the currently
active control location), or if supervision is forced using
parameter 50.26 FBA A comm supervision force.

Drive generates an A7C1 FBA A communication warning
and freezes the speed to the level the drive was operating
Last speed
at. This only occurs if control is expected from the FBA A
interface, or if supervision is forced using parameter 50.26
FBA A comm supervision force.
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.
