DS714F1

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, VFRMS.

E1MODE[1:0]

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

00 = E1, E2 = P1AVG, P2AVG

01 = E1, E2 = S1, S2

10 = E1, E2 = Q1AVG, Q2AVG

11 = E1, E2 = Q1WB, Q2WB

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 P1AVG and P2AVG. 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.
