Looking for some better info on this servo fault and some other Fanuc servo alarms.  Any Fanuc technicians have details or a straightforward, simple explanation for the SP9003 alarm?
Have a good day,

SSPA:03 DC-LINK FUSE IS BROKEN

1 Replace the Spindle Amplifier.

2 Check the motor insulation status.

The Power Supply (PS) becomes ready ("00" is indicated), but the DC link voltage is too low in the Spindle Amplifier. The fuse in the DC link section in the Spindle Amplifier is blown. (The power device is damaged or the motor is ground-fault.)

(this is from the Fanuc manual)
