VFD Has defantly blown up now!

[charlieuk]

New spindle and vfd arrived from cnc4u and I have replaced them wire for wire. Are there any tests I can do to make sure all is ok before I do any damage? We think the fault was at the plug so I have soldered the wires this time as suggested. I did not set up my original and I'm terable at reading (dislexia) and I'm just trying to establish if there is anything that I need to program on it. The new one has a little dial for sped I asume however the old one was set up for the speed to adjust on Mach 3? I'm terafied of turning it on and it going bang again!
