Learning Basic Features
You can set and modify a frequency reference by setting voltage inputs when using the V1
terminal. Use voltage inputs ranging from 0
–10 V (unipolar) for forward only operation. Use
voltage inputs ranging from -10 to +10 V (bipolar) for both directions, where negative
voltage inputs are used in reverse operations.
4.2.3.1 Setting a Frequency Reference for 0
–10 V Input
Set IN-
06 (V1 Polarity) to ‘0 (unipolar)’. Use a voltage output from an external source or use
the voltage output from the VR terminal to provide inputs to V1. Refer to the diagrams
below for the wiring required for each application.
