Hi,
I want to use EtherCAT DC SYNC0 frequency(minimum 2kHz).
But when I try to decrease SYNC0 cycle time under 4ms(250Hz) in TwinCAT, EtherCAT Statemachine is in "ERR SAFEOP".
(running TI example EtherCAT project..)
So, I want to know maximum SYNC0 frequency in use of EtherCAT communication.
Did you ever test this?
