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
page 251).
