Settings
Pr.04-00 ~ 04-03, Pr.04-11 ~ 04-18 are used when the source of frequency command is
the analog signal. Refer to the following examples.
Example 1:

Freq.
60Hz
30Hz
0Hz
4mA
Example 2:
In this example with the potentiometer set to 0V the Output Frequency is 10 Hz. The mid-point
of the potentiometer becomes 40 Hz. Once the Maximum Output Frequency is reached any
further increase of the potentiometer will not increase output frequency. (If you want to use the
range of 60Hz, please refer to the example 3.) The value of external input voltage/current
0-8.33V (4-13.33mA) corresponds to the setting frequency 0-60Hz.
