Structure of a CNC error message

Each CNC error message contains a unique error number and other information that describes the cause of the error as accurately as possible. Also, the error message contains identifiers of the minimum error response that the CNC will internally perform immediately after the error occurs.

For easier diagnosis, the error messages are classified with regard to the cause of the error. Each corresponding error type receives a unique identifier and a data packet, which is always provided with this 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.
