4.1.2 Set the Operation Frequency from the Keypad - Using [
▲]
and [
▼] keys
You can use the [
▲] and [▼] keys like a potentiometer to modify the frequency
reference. Select the Frq (Frequency reference source) code in the Operation group
to 1 (Keypad-2). This allows frequency reference values to be increased or decreased
when the [
▲] and [▼] keys are pressed from the Operation group 0.00 (target
frequency).

4.1.3 V1 Terminal as the Source
You can set the frequency by inputting the voltage from the V1 terminal (frequency
setting voltage terminal) from the control terminal block. 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 the Frq (Frequency reference source) code in the Operation group to 2 (V1), and
then set code 06 (V1 Polarity) to 0 (unipolar) in the Input Terminal group (IN). Use the
voltage output of the external controller or use the VR terminal (frequency setting
power terminal) of the control terminal to input voltage in the V1 terminal as the
volume resistance.
