Hello routercnc, thank you for the advice :)

To be honest, I received my spindle kit more than two months ago and have not yet powered the VFD and haven't looked at the manual much yet (I know there is a good stick thread on here that will help).

Though I know it's possible to control the VFD (run/stop, and speed) with the BOB, I am not sure how the controls actually work. Is the run/stop line of the VFD the equivalent of the ENABLE for the motors ?
