7.3.3 Settings depending on voltage (0 to 5 V) input
<external potentiometer>
You can set the frequency by connecting the FRH kit (optional), or a potentiometer (1 to 10kΩ – 1/4W) to the VI
terminal.
Connect the potentiometer between the P5, VI, and CC terminals. The standard voltage for the P5 terminal is 5Vdc.
Instead of using the potentiometer, you can set the frequency settings by inputting an analog voltage signal of 0
to 5Vdc between the VI and CC terminals.
The following shows examples when the run command is input from the terminal.
