Please see the picture below. At one time, specific USB FaroArms did not have infinite rotation and the arm rotation limit was set to 500. On occasion, the FaroArms would hit the peak and receive an error, informing you that you are about to hit the 500th rotation limit. The fix is to unwind the joint until you see the numbers on the stress stop decrease. This is a simple firmware update and can be performed when the arm is serviced at our facility.
