Notes ------------------------------------------------------------------------------------------------------------
 If the wattage limiter operates, suppress the output wattage within the rated output power by
lowering the output voltage setting value.
 Active power (unit: W) is restricted by the wattage limiter, however, reactive power (unit: var)
is not restricted. Therefore, the apparent power (unit: VA) may exceed the rated power
depending on the power factor of the load. Set the output voltage so that the apparent power
does not exceed the rated power, regardless of the operation of the wattage limiter.
 The value of the wattage limiter cannot be changed. To limit the output power to a value that is
lower than the rating, decrease the number of power units that are energized through the power
unit energization setting, or use the peak current limiter or the RMS current limiter.

4.2 Using Sequence Function
4.2.1 Basics
By using Sequence function, an output setting can be changed step-by-step according to the program
(sequence) created beforehand. This section describes the basics for using the Sequence function.

AC/DC Mode and Signal Source
Sequence function keeps the selection of the AC/DC mode and a signal source, independently from
Continuous function/Simulation function. AC/DC mode can be selected from AC/ACDC/DC. A
signal source is fixed as INT.
