Hello, I recently installed a VFD to my 3 phase south bend lathe… it works great, extremely quiet, etc…
My question is of such nature.
With the VFD I’m using (teco Westinghouse 1hp 115V single phase L510-101-H1-U ) I’m able to adjust speeds of lathe with the VFD from O-60 as default setting, right now I’m running speed #25… AS well I have the speeds on the lathe with 4 belt positions, back gears, etc…
This is a 1hp GE original motor and this lathe although from 1950 has/show minimum usage and well taken care of…
Question- what are the common or a decent recommendation for the VFD speed to be set at? Currently it’s on 25… is this to low? Seems like lathe in 3rd position from left seems ok in speed… Is it a matter of purchasing a rpm indicator?
The answer is prolly on this site, but wow there is a lot on this site and I didn’t see anything online about VFD set speed per lathe?
I’m really like to just leave the belt position on lathe alone and use a few speeds on the VFD by taking speeds on key pad up/down, or setting VFD at 1 speed that puts the 4 belt positions when changed in proper rpm range in which lathe was intended for.
Thanks in advance, pastor Joseph Hart.
