Maybe I missed something in the thread, but it shouldn't be at all difficult
to add several bells & whistles to the VFD.

I'm using the original on/off/reverse (drum) switch on a Clausing
5900-series lathe to control the VFD. I just ran low voltage wire (20
gauge?) between the switch contacts and the control (input) contacts on a
Mitsubishi VFD. One of these days I'll get around to adding a remote pot to
make it easier to change motor speed.

I also just wired a KO Lee surface grinder to an Hitachi VFD. The grinder
has seperate momentary on and off switches and the VFD lacks built in 3-wire
control, but I was able to get around that by wiring in a cheap low power
control relay. Again, the switch wires were run to the VFD control input
contacts.

Well rats, there go all of those nifty bells, whistles and safety
features that made the lathe so attractive when I bought it.

Anyone interested in trading a almost new Teco 3 hp VFD for a good
working rotary phase controller? 8^)

I guess I will be rewiring the lathe this weekend.

It is interesting that when I called Teco tech support today and told
them my tale of woe. Then never even cautioned me about the relays other
that to say I ought to find out why they were chattering. But what they
told me to do didn't work either. 8^(

Thanks again to all that responded.
