Example 1: Standard application
This is the most used setting. The user only needs to set Pr.02.00 to 04. The frequency command
comes from keypad potentiometer.
60Hz
30Hz
0Hz
0V
Example 2: Use of bias
This example shows the influence of changing the bias. When the input is 0V the output frequency is
10 Hz. At mid-point a potentiometer will give 40 Hz. Once the Maximum Output Frequency is reached,
any further increase of the potentiometer or signal 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.
