Re: UC400ETH HY VFD Control

My VFD can accept 0-5V analog which from what I was reading I could put in an RC (Resistor & Capacitor) circuit to smooth the PWM output of my motion controller into a readable analog voltage for my VFD.
I have tested this with a 10k resistor and 5uF capacitor but with no luck.
If anyone has done this before with any success I would love some help if possible. Or any alternatives like PWM to Analog control boards.

Is it possible to use pulse instead of analog?
