Thanks very much. I have subsequently connected and programmed a Teco VFD I have, but getting the same results coming out "inverter overload". I think I am doing something fundamentally wrong and keep going over the programming options to try and discover. I have an clamp meter attached and abort the start-up very quickly as current way over the spindle rating. All help much appreciated.
