    Thanks for all the help guys, this makes things so much more clear! If I understand this right, would using terminals FB & FC have the same result for 250VAC? Sorry if its a daft question as i'm clueless when it comes to electronics!!

    Please if you get the chance could you give the updated schematics a final once over? Only additional thing I changed further to the suggestions was earthing the Spindle to the VFD rather than star point as I guess will make wiring easier.

    I noticed that AliExpress have a sale going on Friday, so would I be OK going ahead and buying the below whilst the deals are on?

    I already have a 80mm spindle clamp but sale price seems to beat all eBay offers I can find for just the spindle/VFD alone

    Schematics

    While the manual mentions KA & KB I think you'll find there isn't any terminals with those markings. Well not on any I've fitted anyways.

    The manual is confusing and I think wrong. On most I've fitted FB is Common and FA =NO with FC=NC manual shows it other way round I think.
    The 3A/240Vac 3A/30Vdc are the ratings of both contacts and not for one set like what manual leads you to think.

    Just wire it like shown and it will work.

    They seem fine to me make sure the VFD is the one in the picture as sometimes they send a different one out.

    Ok few small details.

    The Green wire you have coming off Stepper B (-) I'm hoping is representing Shield going to earth and your not actually taking B(-) to earth.? If correct still only earth at the Controller end not the Stepper end.

    Don't need 24V to outputs 0-3 because your not using any. Your only using the onboard Relay which is output 4 and doesn't need 24V.

    Fans can get away with sharing fuse. I use 2 x 12v wired in series because are cheaper and easier to find.

    With the 24V for Controller I/O save your self some wire and jumper between the Pins. Don't need to run separate wire to each pin. (See pic)

    Don't forget to send Earth to Machine Frame.
