ABB ACS280, Firmware Manual, Page: 383 / 430

Fieldbus control through the embedded fieldbus interface (EFB)
383
depends on the settings of
58.26 EFB ref1 type
and
58.27 EFB ref2 type
. See section
About the control profiles

.
Actual values
Fieldbus actual signals (ACT1 and ACT2) are 16-bit or 32-bit signed integers.
They convey selected drive parameter values from the drive to the master.
Whether the actual values are scaled or not depends on the settings of
58.28 EFB
act1 type
and
58.29 EFB act2 type
. See section

About the control profiles
A control profile defines the rules for data transfer between the drive and the
fieldbus master, for example:
•
if control word and status word are converted and how
•
if signal values are scaled and how
•
functionality and content of certain objects in section
Object dictionary
on
page
400
).
You can configure the drive to receive and send messages according to one of
the four profiles:
•
CiA 402
•
ABB Drives
•
Transparent 16
•
Transparent 32
For the ABB Drives and CiA 402 profiles, the embedded fieldbus interface of the
drive converts the fieldbus data to and from the native data used in the drive.
The Transparent profiles perform no data conversion, but the Transparent 16
profile may optionally scale the reference and actual values with a configured
scaling value (
58.24 Transparent 16 scale
).
CiA 402 profile
Control Word for the CiA 402 profile
Control word of the CiA 402 profile can be written to the object 6040h.
The table below shows the contents of the fieldbus Control Word for the CiA
402 control profile. The embedded fieldbus interface converts this word to the
form in which it is used in the drive.
