Introduction to the diagnostic system
Multi axis servo system - AX8000 11
Version: 1.1
Parameter objects are either standardized CoE parameter objects or Beckhoff-specific parameter objects.
Parameter object Description
0x60xx Standardized CoE parameter objects for the first axis
0x68xx Standardized CoE parameter objects for the second axis
0x3000 to 0x33FF Beckhoff-specific parameter objects for the first axis
0x3400 to 0x37FF Beckhoff-specific parameter objects for the second axis
Layout of the diagnostic system
The Axis Main slot is combined automatically with the Axis Main module. There are several CoE objects
within this module, including the object 0x10F3:xx. This contains information about the diagnostic system.
The subindices of this CoE object contain the following:
Parameter object Description
01 Maximum number of diagnostic messages
02 Latest diagnostic message
03 Latest confirmed diagnostic message
04 Availability of new diagnostic messages
05 Flags
06..255 Memory space for the last 250 diagnostic messages
The structure of the individual subindices is shown in the diagram. The parameter objects of the subindices
are described in detail below.
Structure of a diagnostic message
The following section described the parameter objects of a saved diagnostic message (subindex 06 to 255)
in the diagnosis history object 0x10F3.
A diagnostic message is displayed in hexadecimal notation and contains the following Beckhoff-specific
parameter objects:
• Diagnostic class
• Diagnostic type
• (Error) reaction
• Reset condition
In conjunction with the diagnostic class, some diagnostic messages contain further parameter objects.
Diagnostic class
A diagnostic message is assigned to a diagnostic class. There are three diagnostic classes in all:
Diagnostic class Information
1 Error An error always causes the axis to be stopped. We recommend the following procedure for the rectifica-
tion of errors:
• Disable the axis
• Rectify the error
• Reset the axis, e.g. via the NC error reset
• Enable the axis
• Put the plant into operation again
2 Warning Warnings are displayed, but the AX8000 does not react directly.
3 Information Information is displayed, but the AX8000 does not react directly.
Diagnostic messages of the diagnostic class Error have two further parameter objects: error cause and error
solution.
