Heavier duty VFD control

[Chris Parks]

The VFD we are currently supplying to customers has a removable keyboard which can then be remotely connected back to the VFD using an ethernet cable. I have found an ethernet splitter that enables us to use a second keyboard which has been handy. The manufacturer told us it could not be done but we proved him wrong.

Usually you can use the three phase mag starter to supply a run permit to the drive

Hi,

here are a few pictures of the magnetic starter that came with the unisaw. If this is suitable to use as the on-off switch for the VFD, I'd love to but don't know how it would be wired. I would plan to add in the 10k pot for speed control, and a reverse switch - not for the table saw, but for the lathe that would also use this VFD. Wiring the pot is not a problem - it would be the same as what I have now. But, my current power/reverse setup is an on-off-on switch, with "left" being reverse and "right" being forward. there are 3 wires from this switch going to the VFD. I've attached pictures in this post and the next to show what I have.

Thanks for any help you can offer!
