Fieldbus control through the embedded fieldbus interface (EFB) 239References References for the ABB Drives profile and DCU ProfileThe references are provided by MPPT and does not depend on any user settings.Actual values Actual values for the ABB Drives profile and DCU ProfileThe ABB Drives profile supports the use of two fieldbus actual values, ACT1 andACT2. The actual values are 16-bit words each containing a sign bit and a 15-bitinteger. A negative value is formed by calculating the two’s complement from thecorresponding positive value.The actual values are scaled as defined by parameters 99.08, 99.09, 46.03 and46.04; which scaling is in use depends on the setting of parameters 58.28 EFB act1type and 58.29 EFB act2 type (see page 152).99.09 (with motor nominal speed)99.08 (with motor nominal frequency)0-2000020000DriveFieldbus010000-1000046.03 (with torque reference)46.04 (with power reference)-(99.09) (with motor nominal speed)-(99.08) (with motor nominal frequency)-(46.03) (with torque reference)-(46.04) (with power reference)
