HY VFD controlled by Duet 3 Mini

dhusolo

I have my 110v 2.2kw liquid cooled spindle working. I've got the pump wired to the VFD so when the spindle is running the pump is running. I've been searching the forums for a few days and I can't seem to find anything clear that I need to do for my setup.

I can control the RPM through the dial on the front of the VFD. However I'd like full control through DWC as in being able to use start, stop and change RPMs.

I've seen posts that say since I have a duet 3 mini, using the VFD pins all I have to do is connect:
DCM to GND to ground the VFD and the Duet 3 mini
FOR to out6 on the Duet 3 mini to control RPM

I also have a frequency to voltage converter like this one.

So my question is, what's the correct way to do this so I have full control over the spindle through DWC?

@dhusolo can you provide a link to the manual for the VFD?

@dc42
My VFD is the 110v 2.2kw 80mm spindle purchased from Amazon and is supposedly a clone of this one.

Closest thing I could find from HY is this one

Otherwise the only thing I have from the seller is a paper manual.

@dc42 From what I can see it's the HY02D211B VFD. I've got it kind of working. I can control the speed from S6000 to S7000 but it'll max out at 7000, even if I enter s24000.

RRF version 3.5.4
Wifi Server 2.2.0
DWC 3.5.4

I've got a jumper wire in between DCM and FOR on the VFD
Out6_buff/VFD goes to pulse input +
and VFD GND goes to pulse input -
This is the one I'm using link text
