Attempting VFD program tomorrow

I changed out the potentiometer that Mark(MKSJ) :grin: linked, and now I have a broader band (less sensitive) easier tuning adjustment. :encourage:

:D
Do you have a pic of the one you have? The pics below is the one that was recommended to me,15 turn. But I STILL didn't have time to wire it up because I have quit a bit of jobs for customers to do first.

I'm on the road instill this afternoon, I'll get one then
 
Glad the new pot. is working for you, as I mentioned you probably had a log taper and the new one one is a linear resistance taper. Typically the recommended resistance for VFD speed pots is a 2K to 5K Ohms. If you have a limited speed range say 20-90 Hz, a single turn speed pot works just fine, you do not need a multi-turn. If you have a wider speed range then a 3, 5 or 10 turn is OK, but a lot of twiddling of the knob. I would stick with a single turn if using a standard motor, I do use a 5K 3-turn in some applications. A 15 turn is excessive, and 10K Ohm is a bit too high resistance. See post #15 for the recommended ETI and there is a picture of the pot. If you want a 3-turn then consider the following pot. which is a 5K ETI MW22B-3-5K, I have purchased from this vendor previously.
 
Clough42 really helped dumb some of that stuff down, not sure if yours is at all like mine...no front panel controls? All PC interface?
