4.1.4 Using Frequency Setting Range Limit

You can limit the range of the frequency setting value for the internal signal source by using the
frequency setting range limit. Even if trying to set a frequency 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.
The frequency setting range limiting value is common to both 100 V and 200 V ranges.
For the default setting range, see 11.14.
-------- Notes ------------------------------------------------------------------------------------------------------------
 The frequency setting range limit is useful for the prevention of an unintended frequency
setting when a setting value is rapidly increased or decreased by using the shuttle.

 Operation procedure
1. Push [Limiter] soft-key to select 3: V/F Limiter (or push
window for the voltage/frequency setting range limit.
2. Set values in the [Freq Up]/[Freq Lo] item so that the upper value of the frequency setting range
limit is higher than or equal to the lower limit.
3. Close the window.
