What is Fanuc SP9011 Alarm?

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 SP9011 alarm?
Have a good day,

SSPA:11 OVERVOLT POWER CIRCUIT

1 Check the selected Power Supply (PS).

2 Check the input power voltage and change in power during motor deceleration. If the voltage exceeds 253 VAC (for the 200-V system) or 530 VAC (for the 400-V system), improve the power supply impedance. Overvoltage of the DC link section of the Power Supply (PS) was detected. (Power Supply (PS) alarm indication: 7) Power Supply (PS) selection error.

(The maximum output specification of the Power Supply (PS) is exceeded.)

(This is from the troubleshooting guide in the Fanuc manual)
