First CNC build - VFD wiring question

[Bez]

Cheers for the replies guys :)

Looking through the manual it states its output current at 10A. Its not a fancy VFD just a huflugdung (Huanyeng) special bought from here http://www.cnc4you.co.uk/Spindle/Spi...h-Matching-VFD.

13A plug sounds like a winner to me but I will obviously be careful with other items running on the same ring until I can figure out its own ring for it to sit on.

So looking under the front panel I'm faced with this:



Motor wires are self explanatory so no need to go over those. Where I'm a bit confused is R S T ...... does it matter which one the live and neutral go to? Obviously the earth goes to "9"

I'm using a KK01 breakout board which has a relay output ..... am I correct in thinking this can be used to start and stop the spindle. If so which would be the correct blocks to wire it into from the basic mention in the manual DCM looks like it might be the one but rather than mess things up I'd appreciate any input for people who have run or are running a similar setup.


Thanks again.

Mains input is easy - just use two out of RST, and it doesn't matter which one is live and which is neutral.
Can't help off-hand with the spindle switching as I don't use it at the moment. One day I'll get round to proper spindle speed and on/off control, but I'm not there yet! For the time being, I just use the front panel controls.

Here's what came with mine, should be of some help...

Nice one :) I like pictures like that ....... its like painting by numbers lol

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.




Here is the schematic:


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)
