VFDs?

[graffian]

I am running it in V/F mode. I set all the parameters available in V/F mode. I set the ones you mentioned as you suggested.
and N036[max current] as default which is 19, I also tried 16 and 25 no difference.
The motor is run so it gives spindle speeds from 40 to 4000, then for the optional 60 to 6000 they supply a bigger motor pulley
and for xxx to 10,000 they come and re-set a parameter and charger you $1200 so I am told;-) So the motor should be ok down
to 2hz.
I tried upping the low voltage, ie the 2hz voltage from 12V to 24V and it improved, but still overloaded at a similar point.
They show a graph where they suggest to set n011-n017, not sure if it's just for clarity but they show it with a lot of slope.
If you graphed my figures there wouldn't be a lot of slope?
