Fieldbus control through the embedded fieldbus interface (EFB) 457
Actual values
Actual values for the ABB Drives profile and DCU 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 are scaled as defined by parameters
…
; which scaling
is in use depends on the setting of parameters
