456 Fieldbus control through the embedded fieldbus interface (EFB)
References for the ABB Drives profile
The ABB Drives profile supports the use of two references, EFB reference 1 and EFB
reference 2. The references are 16-bit signed integers.
The reference values can be written to the objects 2102h and 2103h, or alternatively
to corresponding objects in the CiA 402 profile object area, see
Object dictionary
(p.
465
).
The references are scaled as defined by parameters
46.01
…
46.04
; which scaling is
in use depends on the setting of
58.26
EFB ref1 type
and
58.27
EFB ref2 type
(see
the table
CANopen parameter settings for embedded fieldbus interface
).
