Hey guys,
I am having an issue when doing linear moves on a Fanuc ARC Mate 120 ic at full speed. If im running around 1500 mm/s its okay but when I switch to 2000 it will fault the robot(collision detect) and abruptly put the brake on. These robots are on an existing line that we are modifying. This isn't something I have ran into before. They really seem to accelerate really quickly and violently compared to the new exact same model robots on the line. The existing robots have 8 years of hard production on them. I am not sure if this is software advances or someone messing around with some acceleration values. I would try to lower the collision detect sensitivity but the move really doesn't look very nice to start with. I am not doing anything abnormal position wise. I am hoping for some expert opinions on this one. For now I am operational running at 75% speed, but cycle time is a huge issue so I am trying to understand what exactly is happening here.
Thanks for your time,
Kevin
