Spindle control

I wiring my bob like this.
Pin 17 use as spindle output then connect pin 17 to common pin of 5v bob relay.5v relay switch on another 5v external relay module.
external relay module switch the 3 phase motor contactor coil.

Pin 17>bob 5v relay com>ex 5v relay module+DC>contactor coil


After that I think it will work fine.i wired like this but not yet powered the bob.
I have a doubt in mind will it work or not?
Please help.

as yu use externel raly in a row
why you will be fine
a 3phase spindel over a relay is not the best idee it gets heavy egnishen at start

why arent you using a cheep VFD at 50USD

then you got full control

I haven't got any vfd right now.

Contactor Coil voltage is 230v and it is a little coil.want low milli amperes.
If you have a vfd for 40 euros please tell me.

I already watched your YouTube video.
So if i watch again not increase your view count.
