288 Parameters
50.18 FBA A actual value 2 Displays raw (unmodified) actual value ACT2 sent by
fieldbus adapter A to the master (PLC) if debugging is
enabled by parameter 50.12 FBA A debug mode.
This parameter is read-only.

-2147483648
…2147483647
Raw ACT2 sent by fieldbus adapter A to master. -
50.21 FBA A timelevel sel Selects the communication time levels.
In general, lower time levels of read/write services reduce
CPU load. The table below shows the time levels of the
read/write services for cyclic high and cyclic low data with
each parameter setting.
* Cyclic high data consists of fieldbus Status word, Act1
and Act2.
** Cyclic low data consists of the parameter data mapped
to parameter groups 52 FBA A data in and 53 FBA A data
out, and acyclic data.
Control word, Ref1 and Ref2 are handled as interrupts
generated on receipt of cyclic high messages.

50.31 FBA B enable Enables/disables communication between the drive and
fieldbus adapter B, and specifies the slot the adapter is
installed into.
Disable
Disable Communication between drive and fieldbus adapter B
disabled.
0
Option slot 1 Communication between drive and fieldbus adapter B
enabled. The adapter is in slot 1.
1
Option slot 2 Communication between drive and fieldbus adapter B
enabled. The adapter is in slot 2.
2
Option slot 3 Communication between drive and fieldbus adapter B
enabled. The adapter is in slot 3.

50.32 FBA B comm loss
func
Selects how the drive reacts upon a fieldbus
communication break. The time delay is defined by
parameter 50.33 FBA B comm loss timeout.
No action
No action No action taken. 0
Fault Communication break detection active. Upon a
communication break, the drive trips on a 7520 FBA B
communication fault and coasts to a stop.
