I got in touch with tech support today, they are supposed to get back to me.
Hmm. I found that the manual said a jumper needed to be changed on an internal circuit board for this unit to run on single phase. It calls out jumper 7 needing to be moved from pins 1-2 for 3-phase operation to pins 2-3 for single phase operation. So, found the jumper after a little searching. One problem: pulled the jumper off and there are only 2 sockets, not 3. No possible way to change the jumper setting unless it's just removed. Anybody run into this before? I did a search here and it looks like someone had an issue finding their jumper 7 but nothing much else. He never posted a resolution either. I've been searching to see if there is another manual for an updated version of the vfd but they are all the same in that respect so far.
I was living in Seattle when Sweo Drives was bought out by Baldor, then a few years later, Baldor decided to move the production to Ft. Smith, Ark. Not one of the engineers from the old Sweo Drives group elected to move to Arkansas. I picked up one of them for my shop, that company called Practec was started about a year later by the rest of the holdouts. Now that ABB bought Baldor and jettisoned the entire older Baldor drive lines in favor of ABB, those guys are sitting pretty.In case anyone else runs into this, I got in touch with tech support today, apparently a company called Practec LLC is handling that now since Baldor has been absorbed by ABB. For anyone else who may need to contact support about one of these drives, their number is (425)881-8202. Told them about the situation and sent pictures of the phantom jumper. They are supposed to get back to me. Will update with any info.
Not related to your question, anyway by now you know you have something more than capable.
Treat that keypad with kid gloves. You don't want to develop flaky membrane switches after pounding on them all day.
I connect external start/stop switches in three wire control and potentiometer for speed variation. Just something to
think about. People get frustrated with membrane switches and push harder on them when the the frustration level gets
too high.
I going to do the same exact thing with a 5 Hp motor. The choices:Picked up a pretty stout Baldor VFD for peanuts, want to use it to run a 5 HP lathe motor from single phase input. Anyone familiar with this model already and know if it is capable?
