Potentiometer (keypad)
Reference value input through the built-in potentiometer.
The manipulating range can be specifically matched with
parameters PNU A151 to A155, which are described below. You
can assign the frequency inverter’s output frequency to any
potentiometer position. To enable the potentiometer, enter value
00 in PNU A001.
To define the potentiometer’s function, use the following
parameters:
