MRx

Monitoring Space Violated

Kuka · KR C4 compact Controller

What does MRx mean?

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.

Repair Steps

  1. 1

    Inspect the current physical position of the robot manipulator and any external axes to determine if they are inside the configured boundaries of monitoring space 'x'.

  2. 2

    Check the activation status of monitoring space 'x' within the robot's safety configuration (e.g., using the HMI or configuration software). An inactive monitoring space will inherently register as violated, setting the MRx signal to '0'.

  3. 3

    Access the robot's safety configuration software (such as WorkVisual) to review and potentially adjust the boundaries or activation state of monitoring space 'x' to match operational requirements.
