What is Fanuc SV0007 Alarm?

Looking for some better info on this servo fault and some other Fanuc servo alarms.  Any Fanuc maintenance technicians have details or a good, simple explanation for the SV0007 alarm?

What is Fanuc SV0007 Alarm?

SV ALM ANOTHER PATH(MULTI AMP.)

When a multiaxis amplifier was used in a 2-path system across paths, a servo alarm occurred on an axis belonging to another path.

When a 2-path system and multiple servo axes between paths are controlled by a multiaxis amplifier, if a servo alarm occurs on an axis belonging to another path of the same amplifier, the MCC of the amplifier goes down and SV0401 V-READY OFF occurs on an axis belonging to the local path in the same amplifier. Since SV0401 is caused by a servo alarm occurred on an axis in another path, SV0007 is caused together to clearly indicate the fact.

The axis belonging to another path in the same amplifier resolves the cause of the servo alarm.

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