The braking resistor is reusable, if I remember correctly. There have been some comments on similar threads that it might not be necessary with this particular application, but I'm not brave enough to leave it out.

- 3520b lapond powermatic replacement svd-p vfd
I finally replaced the VFD on my 3520a. It works great but I just got a 4224. So there’s that.
Hi Daryl. I just installed the Lapond Model: K100-2R2G1 on my 3520B. I wired it using the procedure given by AAW member John Coppola in 2019. John's procedure is for a Lapond SVD-P-3HP so his programming codes are different.
My question is, how do I know which funtions need changed and what should they be? There are probably 75 or so functions in the K100 manual, how do I know which ones to change?
thanks, Brian
I have used this one for a couple of different machines. It's easy to program, works great, and for under $100, I can have a spare one one ready in case one tanks.

I don't rememeber the whole process off the top of my head, but it wasn't that hard to figure out. The control inputs need to be configured, (so you don't have to try to run your lathe with the keypad) then typically you can adjust the max and min RPM, ramp up/down times, etc.
Here's the summary of parameters for a 3520 vfd. You have to use the manual to know which parameter number corresponds to each item. It's not a long list.
