As promised friends my TinyG dump is posted.
I put it on the forum though so it would be easier to find as time winds by.
This allows me to use the VFD to run my 800w spindle through the tinyG, no extra hardware needed? Run the VFD to the PWM slots?
Chris hit you up on the forum as well, but copied here as well.
Chris - well… sort of.
Yes you can operate your spindle directly from the TinyG. There are settings you need to change in the VFD. Not hard at all. A jumper and your ready to go.
Now the sorta part. We found that it wasn’t a direct correlation. Meaning, that 500 may not be 500. 10k not actually 10k.
We use it bacause we use about the same band of RPM all the time so this works for us. If one needs the ability to use the entire RPM range this is not a great solution. The VFD needs an analoge 0-10v the TinyG puts out 0-3.3v via PWM.
