Frequency setting
I set Pr.79 (Operation mode) to "2" (external operation mode) and use a 2 kΩ frequency setting potentiometer. However, the actual running frequency does not change linearly with respect to turn of the frequency setting potentiometer. (The running frequency is correct for the leftmost and rightmost positions of the potentiometer. However, it is misaligned when the potentiometer is at the mid position.)
Can I adjust this with the inverter's parameters?

Answer
No. Use a frequency setting potentiometer with the resistance of 1 kΩ and B characteristics.
Input voltage is not linear due to the inverter's internal impedance.
