I have been using the VFD to control my spindle prior to trying this setup all worked fine.
It appears you are using a SSR that is totally unsuitable for what you are trying to do.
If I understand it correctly, you are using a 240vac TRIAC output SSR to switch low voltage DC control.
If going with an isolated switch, you need something with a DC logic level output.
