Phase Rotation / Phase Sequence

Phase rotation(aka sequence) in three-phase mode is determined by the programmed phase
angles for phase B and C. Phase A is always the 0° reference and this value can only be
changed when an external phase sync. Input mode is used. For normal operation, the
internal phase A is used as the phase reference for B and C so phase A is fixed at 0° and the
field is disabled. (Light grey instead of black text).
The default phase rotation of the AFX is the same as that of legacy PPS UPC controllers. This
phase rotation is positive so when driving AC motors, the motors will turn forward.
Phase rotation in three-phase mode can be reversed if needed in one of three ways:
1. By swapping output connection wires B and C to the load.
2. By reprogramming the default phase setting for B to 240° and for C to 120°.
3. By selecting "Positive (Phase B leading A)" under "Phase Rotation" in the source
configuration screen.
The reversed phase rotation is shown in the figure below for reference.
