Roboguide test run settings

I use roboguide to make programm for an r30ib ARC mate 120iC/10L. I found one error: when i start my programm in test run mode it works fine, but if i do it in TP i got in singularity error on 90 angle turn. I cant use here J move, real robot got same singularity error. I check some information about this - some people talking about system variables which toggle singularity detection but im not sure it help me with real weld robot
