HLV-H - using VFD strictly to produce 3-phase?
Hello all,
Please forgive me bringing up this subject again; I have read all the posts that I can find about the subject of single/three phase/dc/vfd's/phase converters on this lathe and what I have realized is that I may not (probably don't) understand how the HLV-H's are designed. I am presently looking at what seems to be a decent used example that is 220v. My plan was to buy a similar VFD to the one I use on my Millrite MVN (https://cdn.automationdirect.com/static/specs/gs2drive.pdf) but since the lathe has variable speed already, just set the VFD to 60 HZ and then leave it alone. (Similarly I could look for a digital phase converter to take switch from 230v to 220v 3-phase) My assumption was that the three phase power fed into the HLV-H was transformed/inverted within the electrical panel to run the accessory single phase and dc motors. Is this correct?
Many people are quite adamant that a VFD is a bad idea on the HLV-H. Now I understand that running at a lower/higher frequency will mess with the accessory motors but could I used the VFD simply as a digital phase converter? I realize it does not take advantage of all the benefits of a VFD but in this case I just want a simple unobtrusive way to run the lathe.
Thank you,
Jason Porter
