Table 16 : Network Interface OUTPUT/ Feedback Register Map
Note for metering data including Output Voltage, THVD, Peak Voltage to RMS voltage ratio, Fundamental
Frequency, and Carrier Frequency if data is not available the PQconnect will report a value of 63353 (or
0xFFFF in hex format) to indicate no data is available. The no data available condition is usually trigged by
the filter output voltage being below the minimum fundamental frequency tracking voltage threshold (see
parameter 680).
