hi all,<div><br></div><div>I'm quite bit of rookie in this motion control field.</div><div><br></div><div>I have servo motor connected to AX2003, so I tried to activate this motor with EtherCAT master protocol provided by etherlab.</div>
<div><br></div><div>I compiled and installed ethercat master module and generic ethernet device driver. (ec_master.ko, ec_generic.ko)</div><div><br></div><div>And HWs are like this,</div><div><br></div><div>EK1100</div><div>
EL1088</div><div>EL2088</div><div><br></div><div>I connected ethernet port in PC to EK1100 coupler and connected EK1100 to AX2003 slave drive with ethernet cable.</div><div><br></div><div>Atne then, I executed /opt/etherlab/etc/init.d/ethercat with start command and I got these messages</div>
