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 10 kΩ – 1/4 W) to the VI
terminal.
Connect the potentiometer between the P5, VI, and CC terminals. The standard voltage for the P5 terminal is 5 V dc.
Instead of using the potentiometer, you can set the frequency settings by inputting an analog voltage signal of 0
to 5 V dc between the VI and CC terminals.
The following shows examples when the run command is input from the terminal.
