If equation Type 1 is selected, the polarity sign
si
is acquired based on the sign of the fundamental wave reactive
power; if equation Type 3 is selected, based on the sign of the fundamental wave active power. If equation Type 2 is
selected, results are unsigned.
*1: If equation Type 2 is selected, take the absolute value.
*2: Fundamental wave power factor is also known as displacement power factor (DPF).

si
If the direction of rotation detection is enabled in single mode, the
polarity sign
si
is acquired based on the A-phase pulse’s rising/
falling edge and the B-phase pulse’s logic level (high/low).
