Phase Mode Selection

Setting output parameters when the AC power source is in single-phase mode (FORM1) is
straightforward as there is only one phase to program. Thus, all fields displayed in the
PROGRAM screen apply to phase A.
In three-phase mode, there are two ways to program most parameters other than the
Frequency:
• Coupled
• Uncoupled
Coupled mode means all phases are set and changed to the same value. Thus, Voltage AC
when set or changed applies to all three output phases. This method ensures output phase
voltages are always balanced and is convenient for driving normal three phase loads.
Coupled mode is indicated by the "ABC" status indicator on the right hand side of the status
bar as highlighted below.
Uncoupled means each phase can be set individually. To do
so, the phase to be set or changed must be selected first
using the PHASE key located on the right hand side of the
front panel keyboard. The selected phase (A, B or C) is
displayed in the status bar as either "A", "B" or "C" when in
SINGLE phase mode or "3ph" will be displayed when in THREE
phase mode.
