Set the Frequency Reference using V0, Built-in Potentiometer
You can modify the frequency reference using the built-in potentiometer. Set Frq
(Frequency reference source) to 4 (V0). View the frequency reference at the 0.00 (Main screen)
in the Operations group. Scaling of the V0 input is done with In.38 through In.41. View the
input voltage at In.35.

Setting the Reference Frequency using Input Current (I2)
You can modify the frequency reference using the I2 input terminal at the control board. Set Frq
(Frequency reference source) in the Operation group to 5 (I2) and apply 4–20 mA input current to
I2. Scaling of the input current range is done with In.53 through In.56. View the input current at
In.50.
