Bit of an update on this. I have the driver apart on my bench and have found the cooling fan faulty and a shorted IGBT. The fan is easy but waiting for someone to see if they can get me a replacement IGBT.
With the faulty IGBT removed from circuit the existing fault disappears and now says that it cannot find the motor which is correct seeing as its not connected.
I will update again if I can get the correct parts and get it working.
