5.1 DFR:
● R-phase active energy fundamental: 20-bit accumulator of R phase active energy from
fundamental harmonic
● R-phase status: 8-bit R phase status (see Tabl e 3 2 ). Bit [0] ( BIL ) represents no-load
condition for phase R active energy fundamental.
5.2 DFS:
● S-phase active energy fundamental: 20-bit accumulator of S phase active energy from
fundamental harmonic
● S-phase status: 8-bit S phase status (see Tabl e 3 2 ). Bit [0] ( BIL ) represents no-load
condition for phase S active energy fundamental.
5.3 DFT:
● T-phase active energy fundamental: 20-bit accumulator of T phase active energy from
fundamental harmonic
● T-phase status: 8-bit T phase status (see Tabl e 3 2 ). Bit [0] ( BIL ) represents no-load
condition for phase T active energy fundamental.
5.4 CF2:
● bits [83..56] of configurators (see Tabl e 3 3 )
