ABB ACS880 - References

￭ 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 46.01...46.07; which scaling is in
use depends on the setting of 58.26 EFB ref1 type and 58.27 EFB ref2 type (page 436).
