Hi Expert,
My customer are using F28388S for servo application with Ethercat, they faced an issue that did not report error when Ethercat cable disconnection.
Test condition:
one Ethercat PLC master, one servo product based on F28388S, one servo product based on competitor device.
all three product are connected together by cable and work normally with Ethercat, then disconnect the cable between the master and F28388S product by hand, then on competitor device will report error and register 0x440 will changed from 1 to 0, but there is no error reported by F28388S and the register is still 1.
would you help suggest how to fix this issue?
