Positioning Monitoring (Axis Number)

What does 1105 mean?

This KUKA KRC4 KSS 8.3 message signals an issue with the positioning monitoring function for a specific axis ('{(Axis number)}'), indicating that the axis is not accurately reaching or maintaining its target position. This can be caused by mechanical inaccuracies, incorrect monitoring parameters, or external disturbances, and is suppressed in torque mode if regular monitoring is deactivated.

• The robot axis failed to reach its commanded target position within the configured permissible tolerance.
• Mechanical issues such as excessive backlash, wear, or friction in the drivetrain of the affected axis impacting positioning accuracy.
• Incorrectly configured or overly strict positioning monitoring parameters in the robot controller for the application's requirements.
• External forces, varying loads, or unstable environmental conditions impacting the axis's ability to maintain its commanded position.
• Issues with the motor encoder feedback or the drive's control loop for the specified axis.

Click steps to track your progress.

1. 1

   Verify the target position and motion profile programmed for the specified axis ('{(Axis number)}') to ensure it is realistically achievable without excessive strain.

2. 2

   Inspect the mechanical components of the affected axis for any signs of wear, damage, play, or looseness that could compromise positioning accuracy.

3. 3

   Review the configured positioning monitoring parameters in the KUKA controller and adjust them if they are too stringent for the application's tolerances.

4. 4

   Use the KUKA HMI's diagnostic tools to observe the actual position feedback from the axis's encoder and compare it against the commanded position for inconsistencies.

5. 5

   If operating in torque mode, confirm that SET_TORQUE_LIMITS(..., monitor #OFF) is active if regular positioning monitoring is intended to be suppressed.
