VFD error

Hi Jazz,
OK, thanks for that. I can make the fan quieter with a bit of acoustic treatment.

Clive,
Thanks for the info. Start/stop and pot has worked well for many years on the old VFD so will most likely go with that option.

Jonathan,
Yes, first thought that crossed my mind was that they owe me about £15 or so! I'll email them and see what they say.

I've settled on getting this one to work - if I go down the route of sending it back an insisting on the 2.2kW unit, and it is faulty (or develops a fault), it could be a difficult discussion.

This afternoon I managed to connect up the spindle and when I pressed run it smoothly ramped up to 24000rpm. It ran in the wrong direction, but easy to fix that one. Another step closer . . .

Why bother can't hear the bloody thing when machines cutting and when not using turn it off.?

Personally I would be getting onto them and insisting on the 2.2Kw just for the fact it gives larger cutter choice and if replacement was faulty then I'd be asking for my money refunded and buying else where. You have done nothing wrong running 1.5Kw with a 2.2Kw VFD provided you used the correct parameters for the spindle and infact your running the VFD well within it's capabiltys so better for them as it's less likely to be stressed.!
