Re: [CAD_CAM_EDM_DRO] VFD?

They list 757 485 8223 as a customer service
phone for variable frequency drives

PS they don't seem to list that model in their current
list. It may have been part of another machine they
make and may have not been sold as a stand alone
device. I notice that they make a lot of specialty equipment.

Hi,

I am thinking about adding a VFD to my bridgeport retrofit. I have a J2
head with variable pulleys, so changing speeds manually is not a big
hassle. Also for rough and finish cuts I normally have to change or
regrind cutters too, so I normally don't change the speed during a cut.
What advantange would I have by adding a vfd. I have acquired an old
inverter from the local junkyard. It is Sumitomo model AF3004-2A2, 2.2
kW. Any hints on where to get it's operating instructions.
