IOT signal power from VFD

I recently purchased the PWNCNC spindle kit, not the spindle system. I am wiring up the Iot power strip for my Fein dust collector, and just need some clarification on wiring the VFD. I think I need to jump the +24v in the VFD to T1A then out T1B to the Iot positive, and +24v Common to the Iot negative. This sound right yall?

Actually now that I think about it, I need a digital out signal when the spindle gets over 5500 RPM. So I need to know which channel output signals the T1A channel. I think it’s FM1. And use the FM1 ground to the Iot negative.
