What is Fanuc SP9007 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 SP9007 alarm?

SSPA:07 OVER SPEED

Check for a sequence error. (For example, check whether spindle synchronization was specified when the spindle could not be turned.)

The motor speed has exceeded 115% of its rated speed. When the spindle axis was in position control mode, positional deviations were accumulated excessively (SFR and SRV were turned off during spindle synchronization.)
