8.3.5 Mode Control (Modes)

Address: 16

Default = 0

VFIX

Use internal RMS voltage reference instead of voltage input for average active power.

0 = Use voltage input.
1 = Use internal RMS voltage reference, VF

RMS.

E1MODE[1:0]

E1, E2, and E3 alternate output mode (when enabled by E2MODE).

00 = E1, E2 = P1

AVG

, P2

AVG

01 = E1, E2 = S1, S2
10 = E1, E2 = Q1

AVG

, Q2

AVG

11 = E1, E2 = Q1

E2MODE[1:0]

E2 Output Mode

00 = Energy Sign
01 = Total Apparent Energy
10 = Not Used
11 = Enable E1MODE

VHPF2:IHPF2

High-pass Filter Enable for Energy Channel 2

00 = No Filter
01 = HPF on Current, PMF on Voltage
10 = HPF on Voltage, PMF on Current
11 = HPF on both Voltage and Current

VHPF1:IHPF1

High-pass Filter Enable for Energy Channel 1

00 = No Filter
01 = HPF on Current, PMF on Voltage
10 = HPF on Voltage, PMF on Current
11 = HPF on both Voltage and Current

E3MODE[1:0]

E3 Output Mode (with E1MODE disabled)

00 = Total Reactive Energy (default)
01 = Power Fail Monitor
10 = Voltage1 Sign
11 = Total Apparent Energy

E3MODE[1:0]

E3 Output Mode (with E1MODE enabled)

00 = Power Fail Monitor
01 = Energy Sign
10 = Not Used
11 = Not Used

POS

Positive Energy Only. Suppresses negative values in P1

AVG

and P2

AVG

. If a negative value

is calculated, zero will be stored instead.

AFC

Enables automatic line frequency measurement which sets Epsilon every time a new line

frequency measurement completes. Epsilon is used to control the gain of the 90 degree
phase shift integrator used in quadrature power calculations.
