EtherCAT Communication
CSD7 Servo Drive (EtherCAT)
EtherCAT State Machine(ESM)
The state machine of EtherCAT Slave is controlled by the EtherCAT master.
ESM
EterCAT State Machine(ESM) includes a states defined by EtherCAT. Changes in ESM are
requested by the Master. The Master can record the contents of EMS change requests to be
changed in the Slave AL control register. The Slave checks the result of a state change
(Succeed / Fail) and responds to the Master in the local AL state. If a request for state
change fails, the Slave responds with an error flag.
