4. Advanced Operation
 Step Behavior (Const, Keep, Sweep)
For the intra-Step parameter other than waveforms and phases, the following three patterns can be
set as the method to change values in the step.
 Constant (Const)
Fixed to the value set in the step.
 Keep
Keeping the value immediately before transitioning to the step. That is, the value is changed
depending on the status of the previous step. Although the parameter value can be set even if
the operation type setting is Keep, the parameter setting value is ignored when sequence is
executed.
 Sweep
It changes linearly from the value immediately before transitioning to the value set in the step,
taking the Step Times. In other words, it reaches the setting value after the Step Time passes in
the step. The starting value is changed depending on the status of the previous step.

Const

value in the next step
-------- Notes ------------------------------------------------------------------------------------------------------------
 The Step Behavior for the waveform and phase is always Constant (Const).
 Keeps as many intra-Step parameter setting values as the number of phases in each step based
on the output phase configuration.
 Cannot be set using line voltage in the single-phase three-wire output and three-phase output.
 The rate of crest factor/clip ratio cannot be changed though a clipped sine wave can be selected
as an output waveform in Sequence function. Set these parameters beforehand using
Continuous function.
 Sequence function displays the measured value in Sequence function, which is equivalent to
that of the Continuous function. However, harmonic current measurement (see 4.4) cannot be
displayed.
