INIT:IMMED
Note: In three-phase mode, phase 1 is normally offset by 0º from the internal
phase reference while phase 2 and phase 3 are offset by 240º and 120º
respectively. Therefore, synchronized transient events will occur at
the phase angle programmed for the phase 1 output, but at different
phase angles on the phase 2 and phase 3 outputs.
This is illustrated in the following figure, where the transient occurs at the 90º angle
programmed for the phase 1 output, but at 330º and 210º for the phase 2 and 3
outputs, because of the default offsets for these outputs.
