Figure 48. Active Energy Line Cycle Accumulation
Note that when line cycle accumulation mode is first enabled, the
reading after the first CYCEND flag should be ignored because
it may be inaccurate. This is because the line cycle accumulation
mode is not synchronized to the zero crossing and, therefore,
the first reading may not be over a complete number of half line
cycles. After the first line cycle accumulation is complete, all
successive readings will be correct.
ACTIVE ENERGY ACCUMULATION MODES
Signed Accumulation Mode
The default active energy accumulation mode for the ADE7953 is
a signed accumulation based on the active power information.
Positive-Only Accumulation Mode
If enabled, the positive-only accumulation mode affects both
energy accumulation registers, AENERGYA and AENERGYB,
as well as the CF output pins (see the Energy-to-Frequency
Conversion section). Note that when the positive-only accumu-
lation mode is enabled on a current channel, the reverse power
feature is not available on that current channel (see the Reverse
Power section).
Absolute Accumulation Mode
The ADE7953 includes an absolute energy accumulation mode
for Current Channel A and Current Channel B active energy. In
absolute accumulation mode, the energy accumulation is done
using the absolute active power, ignoring any occurrences of
The ADE7953 includes a positive-only accumulation mode
option for Current Channel A and Current Channel B active
energy. In positive-only accumulation mode, the energy
accumulation is done only for positive power, ignoring any
occurrence of negative power above or below the no-load
