Table VIII. Register List (continued)
Description
Line Cycle Register. The content of this register sets the number of half line
cycles while the active energy and the apparent energy are accumulated in the
LAENERGY and LVAENERGY registers. See the Energy Calculation section.
SAG Line Cycle Register. This register specifies the number of consecutive half
line cycles where voltage channel input falls below a threshold level. This regis-
ter is common to the three-line voltage SAG detection. The detection threshold
is specified by SAGLVL register. See the Line Voltage SAG Detection section.
SAG Voltage Level. This register specifies the detection threshold for
SAG event. This register is common to the three-line voltage SAG
detection. See the description of SAGCYC register for details.
Voltage Peak Level. This register sets the level of the voltage peak
detection. If the selected voltage phase exceeds this level, the PKV flag
in the status register is set. See Table XII.
Current Peak Level. This register sets the level of the current peak detec-
tion. If the selected current phase exceeds this level, the PKI flag in the
status register is set. See Table XII.
PGA Gain Register. This register is used to adjust the gain selection for
the PGA in current and voltage channels. See the Analog Inputs section
and Table X. This register is also used to configure the active energy
accumulation no-load threshold and sum of absolute values.
Phase A Active Power Gain Register. The active power caluation for Phase A
can be calibrated by writing to this register. The calibration range is 50%
of the nominal full-scale active power. The resolution of the gain adjust is
0.0244%/LSB.
Phase B Active Power Gain.
Phase C Active Power Gain.
VA Gain Register. This register calculation can be calibrated by writing
this register. The calibration range is 50% of the nominal full-scale real
power. The resolution of the gain adjust is 0.02444%/LSB.
Phase B VA Gain.
Phase C VA Gain.
Phase A Phase Calibration Register.
Phase B Phase Calibration Register.
Phase C Phase Calibration Register.
Phase A Power Offset Calibration Register.
Phase B Power Offset Calibration Register.
Phase C Power Offset Calibration Register.
CF Scaling Numerator Register. The content of this register is used in
the numerator of CF output scaling.
CF Scaling Denominator Register. The content of this register is used in
the denominator of CF output scaling.
Active Energy Register Divider.
Apparent Energy Register Divider.
Phase A Current Channel RMS Register. The register contains the rms
component of one input of the current channel. The source is selected
by data bits in the mode register.
Phase B Current Channel RMS Register.
Phase C Current Channel RMS Register.
Phase A Voltage Channel RMS Register.
Phase B Voltage Channel RMS Register.
Phase C Voltage Channel RMS Register.
Phase A Current RMS Offset Correction Register.
Phase B Current RMS Offset Correction Register.
