Ok well this confirms my suspicion that you are not correctly in control of the Relay outputs.

First of all you don't calibrate the spindle with Function Config. Set it back to defaults and leave alone.

To sort this your going to have to take a few steps back and deal with one issue at a time. So Forget the speed control for the moment We'll come back to speed and setting it up control later.
Leave external control turned off in VFD, just control speed thru the VFD for now.

Lets concentrate on getting control of the outputs that turn on/off the relays.

First I need to know the position of the Dip switches on the BOB.?
