Can you say to me what may be wrong with this configuration? how I can check if the VFD's are setup correctly, where I can look at that? there is any manual to setup correctly the VFD's? the person who setup (that is not me) left the company so i'm in the middle of this problem and I need to get working.

Thanks for all the support and sorry for my bad english, hope you understand what i'm trying to say.
