Fieldbus control through the embedded fieldbus interface (EFB) 395References References for the ABB Drives profile and DCU ProfileThe ABB Drives profile supports the use of two references, EFB reference 1 and EFBreference 2. The references are 16-bit words each containing a sign bit and a 15-bitinteger. A negative reference is formed by calculating the two’s complement from thecorresponding positive reference.The references are scaled as defined by parameters 46.01…46.04; which scaling isin use depends on the setting of 58.26 EFB ref1 type and 58.27 EFB ref2 type (seepage 294).The scaled references are shown by parameters 03.09 EFB reference 1 and 03.10EFB reference 2.46.01 (with speed reference)46.02 (with frequency reference)0-2000020000DriveFieldbus010000-1000046.03 (with torque reference)46.04 (with power reference)-(46.01) (with speed reference)-(46.02) (with frequency reference)-(46.03) (with torque reference)-(46.04) (with power reference)
