4. Advanced Operation
 Step
The output by the Simulation function consists of six types of steps: Initial, Normal 1, Trans 1,
Abnormal, Trans 2, and Normal 2. Before the simulation starts, this product stands by at the Initial
Step. During the simulation, the step changes in the order of Initial, Normal 1, Trans 1, Abnormal,
Trans 2, and Normal 2. After the simulation ends, this product returns to the Initial Step and stands
by.
 Step parameter
Each parameter of Step Time, AC voltage, frequency, start phase, stop phase, trigger output, and
synchronization output can be set for each step. However, some parameters cannot be set in some
steps.
 Initial Step
Initial Step is assigned to the stand-by state before the simulation starts. This product also moves to
the Initial Step and becomes stand-by state after the simulation ends, except when the repeat count is
specified to 0 (= infinite count).
 Transition Step (Trans 1 and Trans 2)
The Step Times of Trans 1 and Trans 2 can be set to zero for simulating the abrupt voltage and phase
changes. When the Step Time is set to the value other than zero, the set voltage and frequency are
swept linearly at the previous and next steps. Note that the AC voltage, frequency, start phase, and
Stop Phase cannot be set in the Transition Steps.
 Other issues
 The Exit operation is available during the simulation. Performing the Exit operation moves to
the Initial Step. The output remains on.
 You can set the repeat on/off and repeat count for the simulation. When the repeat is set to on
and the repeat count to zero (0), the testing repeats infinitely.

 The Simulation function does not support the standard tests defined by organizations such as
IEC. Use this function for a preliminary testing.
