EtherCat Fault when..

[Stefan009]

Hi.

I have this project with NJ501-1300, in the ethercat settings we add a air valve called EX260-SEC1.
When this unit is alone in the ethercat settings, it works without a problem, as expected.
But when we add the servos that goes into the machine (ED1F CoE Drive (HiWin)) (Or Ezi-Servo2 ALL), then the air valve goes into error, even if the other ethercat
devices are disabled.
 

We have tried both sysmac 1.45 and 1.47, the plc has 1.43 firmware. We have tried to create a new emptyh project and using different computers, the same error pops up when anything else than the air valve are added to the ethercat config.

Any idea how to solve this?

Did you set the correct node numbers on the EtherCAT devices themselves?  Some devices have switches to set node number, while others must be set via software.

Do they match up to the ones shown in Sysmac Studio?

Hi. The air valve uses auto numbering by default, but then you can force the number via sysmac studio, which it accepts.

If its all alone on the ethercat network in sysmac config, it works, but if we add devices and disable those, and only keep the air valve enabled, it does not work at all, no matter which node # you give it.

We noticed last thursday, that if we connect one of the other disabled items to the ethercat cables, THEN the valve works (as alone enabled)..

We have tried using several node # for the air valve, and it doesnt matter.
