It works OK at KUKA Robot "KR 10 R1100 sixx", but I'm not sure it works at other robots.
To install this parameter, start grasshopper, go to "File -> Special Folders -> Components Folder" ,then copy&paste the download file to "Components Folder".(That's all)
After installing the file, I highly recommend you to open the example file to understand how to use this parameter.
