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.
Note: This parameter cannot be changed while the drive is
running.
Normal
Normal Normal speed. 0
Fast Fast speed. 1
Very fast Very fast speed. 2
Monitoring Low speed. Optimized for PC tool communication and
monitoring usage.
3
50.26 FBA A comm
supervision force
Activates fieldbus communication monitoring separately for
each control location (see section Local control vs. external
control on page 20).
The parameter is primarily intended for monitoring the
communication with FBA A when it is connected to the
application program and not selected as a control source by
drive parameters.

51 FBA A settings
Fieldbus adapter A configuration.
51.01 FBA A type Displays the type of the connected fieldbus adapter module.
0 = Module is not found or is not properly connected, or is
disabled by parameter 50.01 FBA A enable; 1 = FPBA;
32 = FCAN; 37 =FDNA; 128 = FENA-11/21; 136 =FEPL;
485 = FSCA.
This parameter is read-only.
