I just got the spec sheet on the spindle and the only thing mentioned is 24,000 RPM and 400Hz.

So... that would compute to be 3,000 RPM per 50Hz assuming that this thing works in a synchronous fashion.

I will update the PD144 parameter.

(Oh and my wiring is reversed - that's why I need to reverse the spindle to cut)

A new version of the plugin is now available.

It's simply fix the problem dealing with CW and CCW rotation (M03 and M04)

It can be download there.

Simply have to replace the old one with this one...

Great, thanks - for now I've gone back to manual control but I'll be checking this out tonight.

I have my Huanyang VFD Spindle working as I would like it, I even have the cooling water pump starting with a relay. But here is the problem, the G-code file starts running before the spindle is up to RPMs I tried adding "G04 P5000"  to the file for a 5 second pause, but the pause is not long enough for the motor to spool up to speed.
So what am I missing?
P.S. Is there a way the get the motor to spool up quicker?

I just found an answer...............  "G04 P5000" should be "G04 P200000" for a 10 second pause.

No need for any of that. You just need to adjust the settings in Mach under Ports & Pins -> Spindle Setup to set how long Mach pauses to wait for the spindle to spin up and spin down.

Thanks Theminor for the reply I'll check it out and see if I can get it working. I'm getting closer to using the water cooled spindle.

Thank for this post. It is just what I needed.

I just purchased one of these VFD's and have decided to try to use VFD plugin to control the VFD through Mach 3 on my CNC router setup.  I have a couple of questions regarding wiring connections.  Does the VFD commumicate with Mach 3 via the RS485 connection.  Is the RS485 connection the only one between the mach 3 computer and the VFD.

Your answer is "yes" & "yes".
go to this link , Sebastien has some photos of the hook-up to the VFD.

Thanks For the answer, sorry I didn't acknowledge you before this but had family crisis that needed to be dealth with.  Also another question or two.  I have a DRO's on the mach3 screen that is labeled AMPS and SPEED what or how do you code that DRO to read AMPS from the VFD, and the Same question for the speed DRO.
