12-3-6 Error Display for MECHATROLINK Slave Station Device Errors
The indicator display shown in the above table indicates that the limit input
has been detected, Servo Drive's main circuit power supply is OFF, or an error
specific to the Servo Drive or another error in the machine or Servo Drive has
occurred.
Check whether the cause of the error is a machine error, a faulty sensor, dis-
connection, or Servo Drive error.
The error types, and the axis in which the error has occurred can be checked
using the PCU Error Flags and error codes.
12-4 Error Codes
12-4-1 Overview
When an error occurs in the PCU, an Error Flag is turned ON and an error
code is input in the Common Operating Memory Area or the Axis Operating
Input Memory Areas.
The area in which the Error Flag is turned ON and the input error code indi-
cate the type of error and in which axis the error occurred.

Error information in this area indicates errors that occur in the PCU or that are
not specific to a particular axis.
The Unit common error code is indicated as 00

hex.
If the Unit Error Flag turns ON, error processing must be performed for the
PCU or the whole system including the PCU.
