I'm not familiar with that treadmill explicitly, but I've designed a lot 
of stuff to run on them, and if you do get to the point where you're 
replacing NV memory and it works (or not), also look at servicing the 
belt.  The load on the motor controller is directly proportional to the 
friction between the belt and the deck.  Over time, without waxing or 
replacing the belt/deck, the load on the motor controller gets worse and 
worse, and finally will become too much to handle for whatever 
motor/controller you put on it.  How long have they been in service?  If 
it's a 3 phase and you just have to replace the controller, look at some 
of the AC Tech stuff - maybe easy enough to just replace the motor 
controller with something similar if you want to take the time to 
customize the parameters on the drive and recalibrate.  This is assuming 
that they're using a 0-10V speed control scheme and not some crazy 
serial protocol from the console.
