Good Afternoon All,
I went to an auction this morning and picked up a Delta 46-745 1642 lathe. Got for $350, so I think I did alright.
It had minor surface rust on it, so I took care of that and lubed her up for a dry run. Once I put it all back together, I plugged it in and flipped the switch. The VFD had both the "power" and "fault" lights lit. I moved the speed control dial back and forth a number of times. The lights stayed lit and I could hear the normal 'hum' inside the controller; but obviously, there was no rotation of the motor.
I do know that this is a 3Ph 1.5hp motor and often times the VFD is particular about the incoming electricity. I tried a number of different circuits (all 20A breakers) in my shop, but it was all via +/-75' of extension cord because the lathe is in my garage and the shop is in the basement. I dont really have room for the new machine down there yet.
So the big question:
How can I troubleshoot the VFD "fault" reading? Are there things I can try in order to eliminate other possible causes for it? Could the length of the cord (14ga) cause this?
Thanks for all the help,
NWB
