2.1

Basic knowledge of the diagnostic system

Control in the AX8000 is monitored by the device itself. Diagnostic messages are generated if an error
occurs in the control process or in the parameterization. In case of an error, all previous diagnostic
messages should be examined in addition to the latest message. All diagnostic messages are displayed in
the TwinCAT Drive Manager 2 and in the System Manager.
Background information: Layout of the firmware structure
The AX8000 has various slots that can be combined with a module. A module is assigned automatically to
each slot by TwinCAT Drive Manager 2, irrespective of the configuration. The modules are already contained
in the firmware of the AX8000.
A module is mandatory for some slots. In other cases the slot is always occupied by the same module,
because only one module is available (see Device Main or Axis Main, for example). Otherwise the TC Drive
Manager 2 chooses between the modules, e.g. sync servo module and linear module for the motor slot.
Fig. 1: Modules and slots - basic knowledge
A module becomes effective and can send diagnostic messages as soon as it is assigned to a slot.
However, the different modules can issue the same diagnostic messages. In order for the cause of each
message to be identified and remedied, it is important to know the origin of the diagnostic message.
Therefore, in addition to the diagnostic message itself, the module that issued it needs to be known.
A module is made up of several CoE objects that contain further subindices (number after the colon). Each
subindex has a pool of parameter objects.
