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

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 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.

Operation procedure
1.
Push [Limiter] soft-key to select 3: V/F Limiter (or push
+
). Opens the setting
window for the voltage/frequency setting range limit.
