    Exclamation Fanuc 18m (+) Button Enabled Continuously

    My Gantry Mill with Fanuc 18m Controls was working fine yesterday morning. Now it is as if the ( + ) key is enabled and will not disengage. I've hard reset the machine numerous times, and checked to see if the key was stuck. As soon as I press the Jog or Home button, then select an axis the machine begins moving in the ( + ) direction. Is there a way to soft reset the CPU ? Any help would be appreciated. Thanks.

    PS. Each axis moves in the ( + ) direction when they are selected. I can move each axis in both directions using MPG.

    A little more info: Last week on 10/14 I installed a repaired power supply by Tri Star CNC. the machine was working fine, but looking back in the Alarm History, since the power supply was installed I have an alarm indicating ' 971 - NMI OCCURRED IN SLC '.
