PROGRAMMABLE AC POWER SOURCE 68
4.1.3 Using Voltage Setting Range Limit
For the Continuous function, when the signal source is INT, SYNC, or ADD, the range of the output
voltage setting value to the internal signal source can be limited. Even if trying to set a voltage that
exceeds the limit, the setting value is restricted to the limiting value. This can prevent mis-setting
when you do not want to set values outside the range.
As for the voltage setting range limiting values, each value is kept independently for the following
settings for 100 V and 200 V ranges respectively: SIN/CLP waveform in AC mode, ARB waveform
in AC mode, ACDC mode, and DC mode.
In case of polyphase output, the setting of the voltage setting range limit is common to all phases,
and kept as the effective value of the phase voltage in this product. When the line voltage setting
(effective value setting) is selected in balanced mode, it is converted into the effective value setting
of the phase voltage according to the following formula and kept in this product.
Balanced three-phase output:
voltage Line
3
1
voltage Phase
 
Balanced single-phase three-wire output:
voltage Line
2
1
voltage Phase
 
The limiting value should be set using the effective value or the positive and negative peak value.
The effective value can be used only when in the AC mode and the waveform is a sine wave or a
clipped sine wave. The limiting value can be set using the line voltage in polyphase output when in
AC mode and balanced mode, and the output voltage setting is a line voltage setting. In other cases,
set using the positive and negative peak values of phase voltage.
For the default setting range, see
11.15 .

Notes ------------------------------------------------------------------------------------------------------------
 The voltage setting range limit is useful for the prevention of an excessive output when a
setting value is rapidly increased or decreased by using the shuttle.
 The limitation is applied to the additional values of the AC voltage setting (recalculated to a
peak value) and the DC voltage setting.
 The voltage setting range limit cannot be applied to the external signal source of EXT and ADD.
 The Sequence and the Simulation function do not include the voltage setting range limiting
function.
 The voltage setting range limit that does not include an output voltage already set cannot be set.
 In the polyphase output, the voltage setting range limit is common to all phases.
 In ACDC mode, set the voltage setting range limit setting using the positive and negative peak
values of the phase voltage regardless of the settings of the waveform, balanced/unbalanced
mode, phase voltage/line voltage.
