References for the ABB Drives profile and DCU Profile
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 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
page 336 ).
The scaled references are shown by parameters 03.09 EFB reference 1 and 03.10
EFB reference 2 .
