Fieldbus control through the embedded fieldbus interface (EFB) 559
References
The ABB drives profile supports the use of two references, EFB reference 1 and EFB
reference 2. The references are 16-bit words each containing a sign bit and a 15-bit
integer. A negative reference is formed by calculating the two’s complement from the
corresponding positive reference.
The references are scaled as defined by parameters
…
; which scaling is
in use depends on the setting of
and
(see
page
).
The scaled references are shown by parameters
