[etherlab-users] control problem in servo motor

[Sebastien Blanchet]

Hi,

Yes your program or your servo drive setup is probably wrong, but nobody can 
really help you because in spite of its length, your report is not efficient enough.

Indeed, writing an efficient bug report is not easy, so if I were you, I will 
first document myself with Google about "efficient bug report" during few hours, 
and then send an effective message to the mailing list so that someone can 
really give me clues to solve my problem.

Anyway the learning curve to setup a servo drive with ethercat is very steep,
so it is normal if the beginnings are hard-working.

good luck
