EtherCAT Communication Unit USER’S MANUAL (3G3AX-MX2-ECT)
3-4 Service Data Objects (SDO)
The EtherCAT Communication Unit for MX2 inverters supports SDO communications as message
communications. SDO communications are used for setting objects and monitoring the status of MX2
inverters. Objects can be set and the status monitored by reading and writing data to the entries in the
object dictionary of the Host Controller.
The following table lists the abort codes for when an SDO communications error occurs.
