AKT2G-AN-400 Object Description and Parameterization


  • Parameterization via the CoE Init-Commands (CAN over EtherCAT)

    The EtherCAT device is parameterized via the CoE Init-Commands tab . Please note the following general CoE notes when using/manipulating the CoE parameters:

    • Keep a startup list if components have to be replaced
    • Differentiation between online/offline dictionary, existence of current XML description
    • use “CoE reload” for resetting changes

The CoE overview contains objects for different intended applications:

The following section first describes the objects required for normal operation, followed by a complete overview of missing objects.
