heres my controlle

I need it in a bit more basic terms so if a diagram with what goes where on the nvem. vfd and relay would be very much appreciated
thanks Dave

This should help, it's basic setup with a diode across the relay to stop back feed from blowing the output up. See Doddy's rough top sketch for diode details.

Attachment 27775

ok great, that seems to make more sense, now do i use the relays that came with the bits i ordered or get new ones that are more suited
Attachment 27776
the 24v and 0v from the power supply to the relay should i take that from the nvsun power supply.

Can't see any reason why not can't use those relays, you won't be using all the contacts but that's not a big deal. Infact depending on the spindle and if water cooled you can actually use one of the contacts to turn on water pump when spindle starts or Vacuum etc.

Yes just use 24v Nv PSU.

Hi jazzcnc
Whats the value of the diode please
thanks

sorry mate,just seen it in your first diagram N4001

OK, Ordered some diodes but have to wait for them,not the same since maplins closed...
jazz will i be able to control the speed via Mach3

Yes and turn it on/off. But you will need to set it up in the spindle control and set the outputs so can turn it on/off.
The manual should tell you how to do this because different controllers have different setups. If you can't find it or it's not obvious then let me know and I'll take a look.

Edit: you will also need to set the VFD up so it knows it's being controlled from an external source. Again the manual will tell you the parameters to set.

thanks for all your help:tennis:

Does that mean your working.?

Just waiting for the diode, the relay all works and if i short PC and STF as the relay would the spindle starts so looks like it will, just want to fit the diode to protect the controller and then i will start the mach3 settings.

HI,
Got the diodes and all wired up but i am not getting the spindle to spin up from mach 3, it seems like the NOVUSON controller is not switching the relay on through mach3.
i have the 24v supply to the relay,the ov from the power supply goes to grd1 on the s axis and the ov from output 1 from the s axis goes back to the relay.
can anyone help me with the settings as i have tried various one from both manuals
thanks Dave
