VFD location

 

Esteemed group members,
Any suggestions where to put the 3hp VFD for my 14.5" tool room lathe? I'm thinking that attaching it to the wall behind the lathe might be the cleanest install for me instead of figuring out where to mount it on the lathe. Any thoughts? Pros or cons as to where it should be. 220V outlet is surface mounted on the wall near the tailstock end of the lathe. Current plan is to mount the VFD on the wall and near the outlet, run armored cable to the lathe and transition to rigid conduit across the back of the lathe to the junction box where the motor wiring is located. Alternatively, I could mount the VFD to the wall near the headstock end and run surface wiring over to the outlet.

Thanks,

My lathe that is up against a wall has a pile of swarf behind it. If your VFD was at the tailstock end it might stay cleaner….

Cheers, al.

George,?

Never install controls behind any equipment. Especially a VFD where you have to reach over the lathe to turn it on and off, and to change speed. Also, remember that those VFDs have tiny display screens, and installing it far away will require you to use binoculars to read the settings ?

Look at the commercial lathes. They all install the DRO/VFD controls on a stand/post either above the headstock, or near the tailstock.?

I am a little partial to a high headstock location, but it is your lathe and install where it is most convenient for you.?

Best Regards,
Andrei

I have mine installed on the wall behind the headstock. ?It never gets hit with any swarf. ?I do have it remote controlled, so I don’t have to reach over the machine. ?A picture is worth a 1000 words.
?
 

I put mine on the wall above the lathe With an outlet that can be used by the lathe, milling machine, or table saw, depending on what I'm doing.

I wall mounted my VFD box, but located the remote pendant on a stalk mounted above the change gear cover.
In addition to the VFD control, I added a hall effect tachometer to it too.
The mount also doubles as a spindle indexing rig.
Mine is on my Logan 922, but I'm only tossing an idea out for consideration.
 

Thank you to everyone that responded!? I think I've settled on VFD attached to the wall and remote control on the stalk where the original Cutler-Hammer fwd/off/rev drum switch is currently mounted. I like the look of the original drum switch, so I might retain the outward appearance and mod the inner workings to match the control circuitry needed for the VFD.? Probably should add a big red stop button somewhere handy because centering the drum switch to the stop position might prove challenging once things go sideways.

That brings me to a side note. I put a 1hp VFD on my Bridgeport a little while ago.? That new VFD cost me just over $200.? I checked prices on the Cutler-Hammer drum switch that I took off the Bridgeport and about fell over!? Sold the old used drum switch on ebay for $200!? A self-supporting hobby! Life is good!

I installed the VFD for my South Bend 16 on the back side of my drive pedestal where the original owner had a disconnect switch mounted. Since the cast?iron mount for the Cutler-Hammer F/R drum switch was broken, I cut the damaged portion off and fabricated?an adapter and mount for my 22mm 5 unit pushbutton control station incorporating Start/E-Stop/Jog/F-R switch/Speed pot control devices. This is the same setup I used on my Wells-Index 55 mill and my South Bend?9A.? The inverter on the 9A was mounted on the backside of the motor cabinet while the inverter for the Wells-Index was mounted on the side of the column where some of the original mechanical table drive components were located.? The mill had been converted to a normal table system using the same motor drives used for Bridgeports.
