Connect spindle with inverter

This guide is for our previous machine but still relevant today. 

Grounding
Most spindles does not have a pin for grounding so you have to do it yourself. If you have a metal clamps for the spindle, you can ground the entire chassis down to earth on your Power supply and then the spindle will be grounded at the same time, otherwise you have to somehow ground the metal casing on the spindle. The manufacturer does not think you need to ground the spindle but do it anyway.

Here is a video on how to wire a spindle and inverter.

Here is some close ups on how to ground the spindle from our user Peter, thank you for the pictures!
