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
