Hey guys,
help needed. I am looking to fit a 10k potentiometer to my VDF and would like to know how ‘you guys’ might have approached it. I have read various online forums and just don’t want to do something silly and make it go boom! this is the model I have…
Thanks in advance…

It is pretty easy. Only took me about 15 minutes to get it working. It’s only 3 connections to the VR, VI, and ACM terminals. The VI connection is the wiper for the potentiometer. VR is 10V and ACM is the common connection.
See page 8 of the manual for the connections. http://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/02/VFD15-22.pdf

exactly, saves having to use the vfd interface everytime. I am really happy with it.
Glad you got it going Simon. It does make life much easier than having to mess with the interface. 
Very nicely done. 
Will the display still show the rpm when using the potmeter?
I’m in the thinking box of buying a X-carve 500 macine and maybe this type of vfd and spindle.
Yes, the VFD display does show the rpm when using the Potentiometer.
Finally some people who got the same spindle and inverter I want to get! Any experience, yet?
Can anyone maybe provide a picture of the power connection of the spindle or even has checked if the enlosure is properly connected to ground? I’ve seen it on some german forums that this is a huge safety issue on many of the chinese spindles.
Furthermore, have you measured runout on those spindles?
