Problem Possible spike in the 24 volt system - CNCzone.com-The Largest Machinist Community on the net!

I am having a problem with my Amada Coma Punch Press running a Fanuc 6M controller. It seems that the 24 volt system is spiking and causing the controller to reset. I believe Diagnosis 804 for my machine is the voltage and it usually runs at around 2400 to 2500 but right before the controller kicks out the number jumps up to 3600 or so. If anyone knows anymore about what might be going on here I could always post more info.
Thank You in advance

Is this happening while the press is moving?
If it is I'd start by checking to see if there are any wires or components on the ram or if there is something being rubbed by the ram while it is moving

yes it happens when the axis are moving, I'm writing a program to run one axis at a time to see if I can narrow down my search. Would a short in the wiring cause what appears to be a voltage spike though?
