ABB ACS850 series, Manual

Page: 235 / 370

Parameters 235
50.12 FB comm speed Selects the fieldbus communication speed. The default
selection is
High . Lowering the speed reduces the CPU load.
The table below shows the read/write intervals for cyclic and
acyclic data with each parameter setting.
*Cyclic data onsists of fieldbus CW and SW, Ref1 and Ref2,
and Act1 and Act2.
**Acyclic data consists of the parameter data mapped to
parameter groups
52 FBA data in and 53 FBA data out .
Low Low speed selected. 0
Normal Normal speed selected. 1
High High speed selected. 2
Very high Very high speed selected. 3
50.15 Fb cw used Selects the fieldbus Control Word which controls the drive.
Pointer Value pointer setting (see Terms and abbreviations on
page 102 ).
-
50.20 Fb main sw func Selects the rule on the basis of which the drive defines the
value for
02.24 FBA main sw bit 1 (Enabled).
51
51 FBA settings
Fieldbus adapter-specific settings.
51.01 FBA type Displays the type of the connected fieldbus adapter module.
0 = Fieldbus module is not found or is not properly connected,
or parameter
50.01 Fba enable is set to Disable , 1 = FPBA-xx
PROFIBUS-DP adapter module, 32 = FCAN-xx CANopen
adapter module, 37 = FDNA-xx DeviceNet adapter module
51.02 FBA par2 Parameters 51.02 … 51.26 are adapter module-specific. For
more information, see the User’s Manual of the fieldbus
adapter module. Note that not all of these parameters are
necessarily used.

51.27 FBA par refresh Validates any changed adapter module configuration
parameter settings. After refreshing, the value reverts
automatically to
Done .
Note: This parameter cannot be changed while the drive is
running.

Bit Name Information
0 Run Enable
func 1 = Parameter only:
Drive writes value 1 to the bit when the external run enable signal (par.
10.11 Run enable ) has value 1.
0 = Param AND Fb cw:
Drive writes value 1 to the bit when the external run enable signal (par.
10.11 Run enable ) is 1 AND 02.22 FBA main cw bit 7 (Run enable) is 1.
