Thor, or should that be Zeus?

i run a heavy load 380v 4kw hydrovane off one- at 50hz. 3 second start up- coast to stop (doesnt like to try to slow down a hydrovane- as they stop near instant when power comes off . it draws just over 30 amp to start it - but drops to 6.9 running it. - so at 380v 50hz they perform well. at 220v i doubt the motor would start at all .
every machine in my workshop is industrial- and they all run off seperate vfds .
if anyone buys the ecogoo 9100 and needs to run modbus- i wrote instructions as they are non existant in the manual!

That sounds good - should suit a lathe where start-up loads are smaller. I don't need the variable speed as the lathe has a continuously-variable pulley system anyway, but I suspect that this is a fairly big load in itself at higher speeds. I'll look more closely at the Ecogoo boxes. Thanks for the pointer.

I think Ill order one, just checking to see what my bonus was for last year (paid next week, yay). Do you have one spare by any chance that I could buy?

i only have my spare here- which i keep for testing - and in case of failure on any of my machines. they didnt take long to arrive

Ok, thanks.

order a braking resistor too 50 ohm 300 watt ( ecogoo stock them around £30)

About to pull the trigger on one of these VFDs. Also very keen to get a Hydrovane. You mentioned a 4KW unit, what model is that?

What current single phase do you have, powering the HSD spindle and the Hydrovane?

Thanks

hydrovane pulls 30 amp for about a second on startup- then drops to 7amp running. hsd never pulls more than 8 amp even when really heavy cutting. - averages around 3a

So, ordered, lets see how long it all takes. I was told I needed a 1000W 50 Ohm resistor, so went for that. Should provide adequate braking for my spindle.
