I recently acquire three viper 200 servo motor drive for a matsuura mill retrofit. In first instance we had no problems with the config of all of them separately, but when we try to run them in the machine some strange happened when we turned on that one of them begin to oscillate violently, and when we check the parameters had different value than we put in.
I think that probably may be noise but I don´t know how can I know exactly what is happening. Can someboy give me some tips to check whats going on?
