VFDs?

[graffian]

Well all didn't go well.
I connected it to the motor it will be running. Set the parameters listed in the 'simpletons guide to getting
started' bit of the pdf. That's just re-setting the V/f parameters to default[which would be a 5kw motor]
and setting a maximum current.
Hit run and the spindle accelerated very slowly to maybe 25 or 30 rpm before an oL2 error appeared. oL2 is
inverter overload. played with the V/f settings, upping the voltage as 12V at 1.5 hz didn't seem a lot.
It accelerated a bit better on the next go, but still really slugish and oL2 error again.
So I whacked it on my coolant pump, I set the max current a lot lower but left every thing else as it was.
The pump doesn't have a plate, probably got washed off, but the motor is a good 6" diam by 6inch long.
It accelerated nice and smooth took it up to 200Hz still pretty good.

So not very promising.
