I need help, at 75 I'm getting stupid . It's pretty frustrating, but what can you do, the other option is looking at grass from the root side. chuckle. When I retired 10 years ago I bought a used lathe, a DF1224g. Without a lathe and welder , a workshop is naked. The electrics were toast, they were running the motor off a cheap toggle switch. I replaced the belts and bearing, as I'm a retired millwright, so that was no big deal. And to deal with the sketchy electrics, a VFD was called for. I got a 2hp 3ph Baldor and the Hitachi WJ200-015SF . I was able to power up, but I was only running the lathe from the VFD control panel .

With the switch wired in I'm only getting a slow creep in forward or reverse. I'm using a drum switch for FOR, OFF, REV . The VFD isn't happy, the fan stays on after a test. . A wild guess from non computer old guy, the programing for the Pot and minimum and maximum isn't correct. THX

When finished I would like to have E-Stop, forward, off, reverse, jog forward, jog reverse . But for now I would be happy with having it run, forward/off/ reverse. I have to make a part.
 
Most likely you need to look at the Hz display and see what speed it is showing, if you setup the parameters for external controls and do not have an external speed pot connected to the inputs or it is connected wrong, the VFD will run at its lowest programmed speed. I have attached some prior directions for the PM-1340GT, parameters should be pretty much the same as well as the wire connections. This requires an external direction control switch and speed pot to be connected. Difference is if you have no contactors then the forward - stop - reverse switch/spindle would be directly connected to the forward and reverse inputs of the VFD see below on sink/source connection. This is 2 wire control so a bit dangerous as the machine will go into a run mode if the switch is not in the stop position. You also want the USPP:Unattended Start Protection) to always be ON, so this should be connected to the source/sink connection that activates the commands. If source connection then this P24 is used as the common to activate the control inputs. This requires the jumper/shorting bar to connect L and PLC.

You do have the VFD connected directly to the motor, yes? No switches or contactors in between?
Just checking
