I am trying to use this relay module to connect the COM and FWD together on my Nowforever VFD. Have I understood the wiring correctly in connecting the relay to AXBB E

Thanks for confirming, i got the spindle working, hurray. The relay trigger jumper had to be set to Low, it was set to high.
Im not sure why that fixed it, but it did :D

That is because the Isolated outputs are N-channel mosfets (NPN), so they pull the signal low when the output is activated.
