Hi, i'm trying to make my servo spin through ethercat and I can't seem to get it moving.This is the kit:
www.omc-stepperonline.com/a6-series-1000...67-a6-ec1000h2a1-m17
I have a simple example without linuxcnc gui, just a .hal file and a ethercat-conf.xml. I can read the feedback values like current encoder position and velocity but I can't make the servo move. When i run the hal file with
halrun -T -kf simple.hal
The drive enables and the fan starts spinning but the servo doesn't even hold position.

note: This one has a brake that I disabled with an external power supply. I can spin the motor with my hand.

I'm new to ethercat in general so any help would be appreciated.

Thank you @onceloved !
It turned out to be a wiring issue

@hellvetica Looks like I have same or very similar issue. What exactly was wrong with wiring in your case?
