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 99.08
, 99.09, 46.03 and
46.04; which scaling is in use depends on the setting of parameters 58.28 EFB act1
type and 58.29 EFB act2 type (see page 152).
