Thanks. The odd part of this is the 2 positon speed switch. But like you say, the switch being engaged to one position or other seems key. Same as what I found with my Rawyler.You won't need or want the overload. The VFD handles all that.
Wire directly from the VFD output to the two speed switch. And remember, don't switch it while the motor is running or you may well fry the VFD.

If anything, I would wire the relay prior to the the vfd. Power>Relay>Vfd> Switch>Motor.
