If you want to do an On/Off control it is a fairly simple matter to wire up a contactor and a control relay. Well maybe not so simple, but definitely not extremely hard either.
You have a 5v signal turn on a low current solid state MOSFET control relay, which switches 24vdc or 110-220vac to pull in a 50 amp rated motor contactor. For the stock lathe it can replace the forward/reverse switch if you don't ever need to run it in reverse.
With the VFD I put on mine it just takes a simple buffered input to turn it on / off from EMC2, and appears to work pretty well. I am very excited to get mine running. |
