Frequency adjustment using potentiometer
When controlling the inverter using the potentiometer, can I read voltage input to the inverter and calculate the speed from the voltage data?
Can I fix * V for *Hz regarding of the output frequency for the analog input 0 to 10 V? Let me know the equation.

Answer
Since the inverter is initially set to 0 Hz for 0 V and 60 Hz for 5 V, you can calculate the frequency for a certain voltage value. The equation is "Output frequency = Voltage × 60/5".
Also, you can use Pr.73 to switch between 0 to 5 V and 0 to 10 V, and Pr.902 and Pr.903 to adjust (calibrate) the output frequency against voltage.
