Set the Frequency Reference using the V1 Terminal
You can modify the frequency reference using the V1 input terminal at the control board. Use
voltage inputs ranging from 0 to 10 V (unipolar) or from -10 to +10 V (bipolar) for both directions,
where negative voltage inputs are used for reverse operations. Scaling of the voltage range is done
with In.08 through In.11 (unipolar) and In.12 through In.15 (bipolar). View the input voltage at In.05.
4.1.3.1 Setting a Frequency Reference for 0–10 V Input
Set parameter Frq in the Operations group to 2 (V1) and set parameter In.06 (V1 Polarity) to 0
(unipolar). Connect an external 0-10V source (PLC or other) to the V1-CM terminals. When
connecting a potentiometer, use the VR terminal (voltage reference, +10V) as the 10V source. See
connection diagrams below.
