Thanks for your help guys its all up and running now :)
Hi guys,
I just bought the KKO1 BOB, I'm trying to to hook it up to the DIYCNC spindle board and then onto the VFD so i can have Mach 3 Control. I would also like to use the spare relay from the KK01 for on/off of a vacuum table lets say. Is any one able to confirm the wiring it correct. I really don't want to blow up any more components. the two links below are for the manuals. many thanks

Hold on ! Looks like you are switching the spindle on and off at the mains input to control it. If you want to start and stop the spindle this is not a good idea! Leave the VFD powered directly from the mains all the time and control it using the green inputs on the control panel - the row of small terminals above the mains and spindle connections.Quote:

This is how I think it should work:
Start / stop = connect relay terminals to FOR and DCM. The relay makes or breaks this circuit.
To get this to work you also need to set PD001 to 1 (from memory) to tell it to use this external control.
Speed control (manual) = connect a 3 pin potentiometer (say 10k) with one outer pin to VR, the opposite pin to ACM, and the middle pin to V1.
To get this to work you also need to set PD002 to 1, and set the little jumper (on the right side of the green input panel) to VI to tell it to use the external control
Speed control (auto with voltage control) = connect 10V from BoB to V1 (as you have drawn it), and 0V to ACM (not as you have drawn it to A1 which is for current control and it looks like your BoB is outputing a variable voltage)
Hi OK, thanks for that and the extra info.
for the interest of this thread I've redone the schematic just so there's no one else following committing to fry their electronics.
Does this look correct? Many thanks

Don't connect anything to VR or AI for what you are trying to do.
Also, note that the manual shows a grounded shielded cable for the control cable (the dotted hoop around the input lines) to reduce interference.
*If any moderators are reading this it is probably more appropriate to move it to the electronics > VFD section . . .*
