JF
Mastering Error (Space Monitoring Deactivated)
A mastering error has occurred because at least one robot axis is not correctly mastered. This condition is indicated by the 'JF' signal being '0'. The consequence of this error is the deactivation of space monitoring functionality, which can compromise the safety system's ability to monitor robot position relative to defined workspaces.
MRx
Monitoring Space Violated
A defined monitoring space, identified by 'x' (where 'x' ranges from 1 to 16), has been violated. This indicates that the robot manipulator or an external axis has entered or is currently within a restricted or forbidden zone. The signal state '0' signifies a violation, and an inactive monitoring space is also considered violated by default, resulting in a '0' signal.
