What is Fanuc SV0301 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 SV0301 alarm?

APC ALARM: COMMUNICATION ERROR

Since the absolute-position detector caused a communication error, the correct machine position could not be obtained. (data transfer error)

The absolute-position detector, cable, or servo interface module is thought to be defective.

(from the Fanuc service manual)
