Learning Basic Features

4.1.2 Keypad as the Source (KeyPad-2 setting)

You can use the [▲] and [▼] keys to modify a frequency reference. To use this as a second option,

set the keypad as the source of the frequency reference, by going to 07 (Frequency reference

source) code in the DRV group and change the parameter value to 1 (Keypad-2). This allows

frequency reference values to be increased or decreased by pressing the [▲] and [▼] keys.

4.1.3 V1 Terminal as the Source

You can set and modify a frequency reference by setting voltage inputs when using the V1

terminal. Use voltage inputs ranging from 0 to 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 reverse operations.

4.1.3.1 Setting a Frequency Reference for 0–10 V Input

Set code 06 (V1 Polarity) to 0 (unipolar) in the Input Terminal group (IN). 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.
