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?
Email Yaskawa time?

Well spoke to a bloke at a place that advertises as a yaskawa motor and drive supplier, reconed
the drive and motor were developed for matsuura and they had mended original drives as they couldn't get
them working with new drives!
Had an email today from yaskawa, I had outlined the problem and asked about solutions, bloke suggested
either installing the original drive, or fitting a generic 3phase motor and vfd.
So looks like I am going to be fitting another motor.
