I HAVE A 412 INTERACT WITH A TNC 2500 AND I HAVE MOVED THE MACHINE TO A DIFFERENT LOCATION AND WHEN I BOOT IT UP I AM GETTING A "SPINDLE DRIVE FAULT". I HAVE SWITCHED WIRES THINKING IT WAS A POLARITY ISSUE BUT NOTHING GOOD. THE MACHINE RAN FLAWLESS BEFORE I MOVED IT TO ANOTHER LOCATION. HELP NEEDED, PLEASE. THANK YOU

Check all connections by turning the power off and test tightening all screws, that's where I would start. Not only the main power conductors, there might also be some skinny wires going to a terminal strip on the drive, and some of those can be on a 'fault reset' type circuit. Gently pull on the wire at every crimped connection to make sure the crimp is holding good.
