Kuka KR C4 compact

This error indicates that at least one robot axis is not mastered, which subsequently deactivates the space monitoring function. The 'JF' signal's state '0' signifies an active mastering error, while '1' indicates no error. This condition poses a significant risk as it disables critical safety monitoring capabilities.

This alarm signifies that a defined monitoring space (ranging from 1 to 16) has been violated by an object or part of the robot. An inactive monitoring space is also considered violated by default. When violated, the associated safe output MRx transitions to state '0', indicating an infringement that could lead to collisions or safety zone breaches.
