Great! Thank you very much.

One last question, if you don't mind. just what should the rating for the braking resister be? I'm not sure I'll add one, but there have been times that I've wished I could get the spindle slowed quicker.

This can be a tough one as some of these VFD's don't support a Braking Resistor,( Just some electronic parts missing ) I have never used one on these Huanyang Drives, some have though with good success, most VFD manufacturers have them already sized for each VFD size,these are for a normal 50/60Hz AC motor, yours is not a normal AC motor, and with not all the spec's available for your spindle, it can be hard to calculate for the correct size, so most that are using them are kind of guessing, I have attached a PDF that give information on how to calculate the Resistor size, but you may not have enough spindle motor spec's, to get it totally correct, I will see what else I can find as this comes up from time to time

Just an update (said I would).

My 4 HP, Huanyang VFD I bought is still working after 6 years now.

Maybe I am just lucky.

What spindle motor are you using with this drive? Has it also lasted this long?

You sized your VFD bigger than the spindle motor requirements, this is always the best idea to help with getting a long life from these drives or for any VFD Drive that is using single phase supply, having the Parameters set correct and wiring correct you have a long life as a result, most of these VFD Drives only fail from incorrect sizing of the VFD Drive bad wiring and Parameter setting

I have more than 15 years on some of my VFD Drives that run everyday
