Umrüstung einer Sinumerik 3T 3-Achs Drehmaschine

I can not help with the scales, but that is for sure a +-10V controlled servo drive, so 7i77 will do nicely.
Do not disconnect the tachos or anything from the drives. Only disconnect the +-10V and the enable so you can wire them to the 7i77. Chances are the velocity loop is all good if the drives are ok, and that you can easily check with an empty batery.

Hello again,

i have now received my new 7i77. Could anybody help me what pins has to be wired?




Hope anybody could help me

Thanks a lot and best regards!
