Fieldbus control through the embedded fieldbus interface (EFB)
ABB Drives profile scaling from fieldbus to drive
The scaled references are shown by parameters
03.09 EFB reference 2
and
03.10
EFB reference 2
.
Actual values for the ABB Drives profile
The ABB Drives profile supports the use of two fieldbus actual values, ACT1 and
ACT2. The actual values are 16-bit words each containing a sign bit and a 15-bit
integer. A negative value is formed by calculating the two’s complement from
the corresponding positive value.
The actual values can be read from the objects 2105h and 2106h, or alternatively
from corresponding objects in the CiA 402 profile object area, see section
Object
dictionary
on page
400
.
The actual values are scaled as defined by parameters 46.01 … 46.04 ; which
scaling is in use depends on the setting of parameters
58.28 EFB act1 type
and
58.29 EFB act2 type
.
