hi all, I'm quite bit of rookie in this motion control field.
I have servo motor connected to AX2003, so I tried to activate this motor with EtherCAT master protocol provided by etherlab. I compiled and installed ethercat master module and generic ethernet device driver. (ec_master.ko, ec_generic.ko) And HWs are like this, EK1100 EL1088 EL2088 I connected ethernet port in PC to EK1100 coupler and connected EK1100 to AX2003 slave drive with ethernet cable. Atne then, I executed /opt/etherlab/etc/init.d/ethercat with start command and I got these messages [ 43.502737] EtherCAT: Master driver 1.5.1 0f7a243b03e4 [ 43.504260] EtherCAT 0: /dev/EtherCAT0 has made [ 43.504264] EtherCAT: 1 master waiting for devices.

What is the problem? Is there any configurations or files for slave devices? I don't know how to connect my host pc to the slaves! I can't proceed my work because of this problem. I will wait for someone's rescue. Best Regard. -CJ-
