Parameter Description
Here are some examples:
Example 1: This is the most used setting. When the inverter is at the external mode, the combined
mode 2 or the combined mode 4, the frequency is set by terminal 2-5.
Example 2: This example shows the effect of changing the bias. When the input is 0V, the output
frequency is 10 Hz. At the mid-point, the potentiometer will give 40 Hz. Once the
maximum output frequency is reached, any further increase of the potentiometer or
signals will not increase the output frequency. To use the full potentiometer range,
please refer to Example 3. The value of external input voltage/current 0~8.33V
corresponds to the setting frequency 10~60Hz.
Example 3: This is another frequently used method. The whole scale of the potentiometer can be
used as desired.
