No action / uint16Selects how the drive reacts upon a fieldbus
communication break. A time delay for the action can
be defined by parameter 50.33 FBA B comm loss
timeout.
See also parameter 50.56 FBA B comm supervision
force.

1Drive trips on 7520 FBA B communication. This only
occurs if control is expected from the FBA B interface
(FBA B selected as source of start/stop/reference in
the currently active control location), or if supervision
is forced using parameter 50.56 FBA B comm
supervision force.
Fault
2Drive generates an A7C2 FBA B communication warning
and freezes the speed to the level the drive was
operating at. This only occurs if control is expected
from the FBA B interface, or if supervision is forced
using parameter 50.56 FBA B 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.
Last speed
3Drive generates an A7C2 FBA B communication warning
and sets the speed to the value defined by parameter
22.41 Speed ref safe (when speed reference is being
used).
This only occurs if control is expected from the FBA B
interface, or if supervision is forced using parameter
50.56 FBA B comm supervision force.
WARNING!
Make sure that it is safe to continue operation
in case of a communication break.

4Drive trips on 7520 FBA B communication. This occurs
even though no control is expected from the FBA B
interface.
