Hi everyone, I have what might be a simple question. I am in the middle of cleaning up a 1971 PM 66 table saw. Bearings belts and the normal items. It is a 3 PH 3 HP motor and I bought a simple VFD off ebay. I fired it up this week and it runs and sounds awesome. I bought a normal paddle on/off switch. The switch is similar to what I saw on the Sears higher end table saws. It is an intermittent switch. In setting up the remote on off for the VFD, the saw will only run when I hold down the on button. I would think there is an setting for that but I do not find anything in the manual. It is a Huanyang advertised as UK USA shpping. Has anyone run in to this issue? THanks for any help.

Try wiring it with a simple toggle switch just to check
if the problem is the paddle switch design.

The VFD that I’m using for my lathe has a setting for using either a momentary or continuous open/close switch. I’d imagine yours does as well.

Loren it is the paddle switch design. A regular light switch works fine.

Cook I have to think that mine has that function, but I can not find it anywhere. That is why I was hoping someone had the same Ebay unit I have. Thanks for the input.

Oops, I just noticed I did not reference the Ebay source in my first post.

Are you sure it’s a mechanical switch and not a
magnetic switch?

I’m kind of grasping at straws. A magnetic switch
needs power to stay on. A mechanical switch
will often have the buttons stay down with
no power. Some magnetic switches don’t
do that.

Loren no mag switch. I’ll post a picture of the switch in a bit.

I downloaded the manual for your VFD and couldn’t find a setting for momentary-vs-latched on/off switch. I think you’re either going to need a different switch or to add a relay to keep the circuit closed.

OK cook. I was pretty sure I looked through the manual pretty well. Some times the nomenclature is a little weird, so I wanted some other input. Thanks.

the cook is right, it sounds like your switch is a momentary on/off switch. you’ll need a relay in the system to function as a set of holding contacts to keep the saw running. can you post a link to the manual or a picture of the vfd’s terminals?

btw, i noticed you’re in terre haute. i grew up in clay city.

Hey Bent, I just bought the new switch, but I do not think it will work. I found an $8 switch that is not intermittent, I was going to buy that, which is fine. I am surprised as much functionality that is in the VFD it will not do this. No big deal really. I will take a quick pic of the terminals.

BTW moved here from Seattle….......yea people still say WHAT! from WHERE!
