If your Spindle of CNC 6040 or CNC 6090 mini CNC router does not work, how to test the spindle?

Today let our ChinaCNCzone team share with you the testing process

First of all, connect everything correctly. I would like to remind you of something very important. If you didn't connect right, some wires will be burnt, spindle have sounds, but no move.
And VFD indicates error.

After you test it,
1 connects to W (the reading was 001 to 000) 

2 connects to V (the reading was 001 to 000)
There was no reading (no result) when 3 connects to U

1) You need to test them step by step,

2) If there isn't any result, please open connectors to check any wires are burnt.

3) If there is result, please open connectors, wires on controller are burnt or not .
