After trawling through countless online videos and documents to wire up the Huanyang 2.2kw VFD I was finally confident enough to get the wiring correct. Taking the plunge I got all the wires in the order depicted in the many documents.
Plugged in and switched on. After what appeared to be a lifetime waiting the inverter kicked into life.

My next step was to get the programming out of the way, this also was successful. Pressed run and the spindle started turning.

Now this is where it all went wrong. I wanted to see how fast the spindle was turning and pressed >> button a few times might and various modes were selected. I considered that I had changed the programming somehow since i had, had it running.

My only course of action was to start again. When I had completed the program inputs. I switched the unit back on and "Bang" all the power went off in my workshop and smoke pored from the unit.

Now prior to the spindle working okay and me attempting to fix things via programming I was pressing the Run btn, the spindle behaved strangely to this in that it would sort of chug round a couple of times the unit went into error.

Could the spindle have been at fault, if so how could i test it without an inverter? Is it possible to sick a 13amp plug on it and connect it to an outlet?

Don't want to get another inverter and blow that up due to a faulty spindle.

And all I wanted to do was to see the RPM and my next step would have been how to adjust the speed.
