Hi ivars,

3000mm/min on 1605 ballscrews at 36V sounds about right based on the spec and speed of my machine. I'm using 1605 ballscrews with an all-in-one board at 24V and get around 1500mm/min before stalling.

I've just returned a faulty VFD that went bang when I wired it up - it was the same model as yours and the supplier asked me for a photo of my wiring. Once he saw that he was happy to exchange it. I had only connected the mains supply (not the spindle yet) and he never mentioned having to connect a spindle, so if such a lockout feature does exist it's not on that model.

Very pleased for you anyway - I remember how good it feels to finally get some movement out of your first machine. Oh, and do move that monitor back a bit when you are cutting chips!
