-12 VMAX IMAX VARh.
0x8A
VAR1SUM_X

VAR2SUM_X
WSUM_X and VARSUM_X are the signed sum of Phase-A, Phase-B and Phase-C Wh or VARh values
according to the metering equation specified in the control field EQU[2:0] (I/O RAM 0x2106[7:5]).
WnSUM_X is the Wh value accumulated for phase n in the last accumulation interval and can be computed
based on the specified LSB value.
For example, with VMAX = 600 V and IMAX = 208 A, the LSB for WnSUM_X is 0.135 Wh.
5.4.8.1 Instantaneous Energy Measurement Variables
InSQSUM_X and VnSQSUM are the squared current and voltage samples acquired during the last accumulation
interval. INSQSUM_X can be used for computing the neutral current.
