Table 4-1 Wattage Limiter Value per Phase (Reference value, Unit: W)

Rated output
per phase
Note: Power input 100 V system is for power input voltage 170 V or less.
-------- 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.
 When the power input voltage is 170 V or less, the maximum output active power of a model
with the rated power of 6 kVA or higher is limited to 4.725 kW of maximum output active
power by the wattage limiter. However, for a single-phase three-wire model and a three-phase
model, the maximum output active power per phase is limited to 4.725 kW/2 and 4.725 kW/3.

Using Sequence Function

4.2.1 Basics

By using Sequence function (optional), 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 output function/Simulation function. AC/DC mode can be selected from AC/ACDC/DC.
A signal source is fixed as INT.
