Spindle Speed Control

Hi Jim
If you post some pictures of your VFD it may be possible to identify it and source manual for it.

Thanks Kn8, here are some pics of the vfd and spindle.






Edit:
Just found the front cover for the vfd in a box of bits! It doesn't have a model number but it does say "240v 1.5Kw".
I've had this thing for over a year and never spotted it, what a spanner!

That looks like a Huanyang Inverter I have sent you a PM.

So with the manual supplied from Kn8 (thanks again!) it looks like I have a HUANGYANG HY01D523B 1.5 Kw VFD

Next step is to sus out how the vfd has been configured and see how that matches up in mach 3...

I guess it's possible to have a potentiometer supplying 0-10v to the vfd for complete manual control? Has anyone done this?

Although I think you're not far off getting the current version working as it looks like just a scaling issue.

Make sure you clean the collet before putting it in the spindle. In the picture there's wood dust inside the collet. This is a quick way to damage the spindle taper and increase runout...

Jonathan - Wow I like the amount of control/feedback you get with the plugin - This may be a future upgrade! Thanks for the collet tip

m_c - Thanks for the step by step info - the motor tuning page of mach 3 scared the crap out of me to begin with but its starting to make sense now - I will give this a try when I get the spindle fixed......I somehow managed to snap off the gx16 connector off the top of the spindle. Luckily I had planned to replace the 3 pin gx16 with a 4 pin one to earth the spindle and have the parts ready to install :)

Just an update...

Spindle now fixed and earthed (with shielded 4 core cable and 4 pin gx16 connector).

Also I have tried configuring the spindle as per m_c's instructions and I now has full control over the speed. Needs a little bit more of a tweak but I'm on the right track.

Thanks to everyone who helped in this thread.
