The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

Thanks for the image :) I see what you mean.

Now, when you open the spindle cap, you just solder a wire from pin 4 to the spindle shield ? I mean, literally to the metallic shield right under the cap ?

Ok it depends if you have 3 or 4 pins on your spindle socket if you have 4 one of them may not be connected to anything. I took the end cap off and soldered a wire to the vacant pin and put a longer screw in the socket and attached the wire to a ring connector which then fitted over the longer screw and fastened it with a nut inside. Then you can use that pin as the earth in the plug. If you only have 3 pins in the socket then you have to attach the earth to the spindle or clamp.

I think the first post of this thread needs to be updated with the following information:

• If you're controlling the spindle speed from Mach3, you also need to:
  - set PD002 to 1. It might be done automatically, but it's worth checking.
  - change the jumper on the right side of the VFD control terminal to VI instead of VR
• Set PD070 according to your BOB's specifications. It is the input voltage that the VFD receives on its control terminal. My BOB sends 0-10V, so I had to change the setting. Check the manual for more information.
