This is strange, I dont have a real answer but I would check the tasks' configurations. Is the initialization running under the fieldbus task? Or in a different one? I would prefer having everything running under the fieldbus task.
If fieldbus is Ethercat, are you using a distributed clock? Is this correctly set (also on the drive side).
Thanks very much!
Yes, the fieldbus is EtherCAT, what is so strange that it is ok in most time of getting up, but failed in startup occasionally
