    A Fanuc 414 servo alarm is generated by the CNC when it detects that an amplifier has a high current alarm 8, 9, or A. To determine the exact cause, you must go through the process of elimination. The high current alarm may be caused by the servo drives, amplifiers, modules, motor and/or cables.

    In some instances, this alarm may indicate a short to ground. The short is causing too much current to flow through the power module inside the amplifier and will eventually cause it to break.
