AC servo drive IS620NT5R4I

•The maximum data capacity of an EtherCAT frame can reach 1470 bytes. Data can be modified or added during message transmission without stacking, caching or decomposition/combination;
•Each node directly uses hardware to implement operations without software participation, which greatly shortens the message delay. The delay of a servo axis is only 1us.
•Each EtherCAT slave has a clock mechanism inside the slave controller ESC, called the slave clock;
•Each EtherCAT master also has a clock mechanism inside, called the master clock;
•The EtherCAT network uses the first slave clock as the reference clock, and the reference clock as the system clock for the entire system. All clocks, including the master clock, are synchronized to the reference clock;
•In the EtherCAT network, distributed clocks can use synchronization signals (SYNC signals) to enable all EtherCAT devices to use the same system time, thereby controlling the synchronous execution of tasks on each device;
•The SYNC signal sending period is the synchronization period.
