In genaral nowadays we don't add new EtherCAT servo or stepper drives into the database as a rule. There are just too many variants now. So the way it is tackled is to use Motion Perfect v5 to process the ESI file from the vendor and generate an EtherCAT Extension file (EC_EXTEND). It can be done using any of our EtherCAT masters, including the Flex-6 Nano.
