Define the type of data that will be exchanged in the PDO PDO is a type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. between the device and the nodes. For the AKD drives, proceed as following to select the standard KAS/AKD system PDO (PDO Assignment):

1. Select an EtherCAT ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs node (Drive 1 (AKD)) and select the “Process data” thumbnail.
2. Select in the “Synch manager” window, Input item then “0x1B20” in the “PDO Assignment Window”.
3. Select in the “Synch manager” window, Output item then “0x1720” in the “PDO Assignment Window”.
4. Repeat the operation for drive 2.
5. Perform the same kind of operation for the non-standard items.
