Thank you very much for your input. I was kind of afraid of that. I've been running into roadblocks across the board trying to get information about this robot. The OEM of the piece of equipment that the robot is attached has locked out all IP with this particular model. Kawasaki flat out told me they could not provide any information to me and I need to communicate with the OEM.
I'm working on verifying the safety signals, as you suggested, but its a little more challenging without schematics or documentation.
If anyone else has any experience with this type of robot, I would welcome any suggestions/commentary. Thanks!!
