Hello KRATMEL,
in appendix you have our example .
We made NMT conection and it is OK. We go in PreOperational mode but when we sent SDO and PDO we not go to Operatinal mode and on drive no any action. Also we tray to set transfer speed to 250kB, 500kB, 1MB... On Drive we not have any error.
Later I tray to change the NOD from 2 to 3 or 4 just like you suggested .
