I just purchased a 1980 model Powermatic 72 table saw which has a 5hp 3ph Baldor (184C frame, Des B, Class F)
I have dedicated 200 amp single phase service in my home shop so I needed a way to power the saw from that. I've had less than stellar results with single phase motors over 3hp at my day job (air compressor and vacuum pump service) so I wanted to find a way to keep the 3 phase motor installed on the table saw. I got the Teco A510-2010-C3 VFD on the advice of tech support from one of the major online retailers for VFD drives.
My question is regarding the start stop switch for the saw, the saw already has a starter box with start / stop control on it however it is 3 phase. I know the VFD has to be connected directly to the motor and the start / stop buttons on the VFD controller are quite small and not ideal for a table saw application in my opinion. It looks as though there are two ways of accomplishing adding another start / stop controller but I wanted to confirm that I am on the right path:
1.) install a single phase start / stop button downstream of the breaker and upstream of the VFD. In this case the VFD would need to have auto-restart option turned on so that it would automatically power on when power is applied.
2.) the VFD has digital inputs for FWD / Stop (also has REV/ Stop but I don't believe I would need that for my application). To use this digital input what exactly would I need? Most of the control panels I deal with have single VFDs being controlled by a PLC that sequences several motors, so this application is a bit different for me.
