Structure of a CNC error message

Every CNC error message contains a unique error number and further information which describes the cause of the error as exactly as possible. The error message also contains identifiers of the minimum error reaction that the NC internally performs directly after occurrence of the error.

To simplify diagnostics, the error messages are classified with regard to causes. Every corresponding error type is assigned a unique identifier and a data packet that is always provided with the specific error type. These data packets (error roots) are described in the chapter entitled Error Types.

They also include up to nine further parameters that contain additional information and, if applicable, provide limit values or incorrect internal control system values for display.
