1105

Positioning monitoring {(Axis number)}

Kuka · KSS 8.3 System Software

What does 1105 mean?

Positioning monitoring has been triggered for a specific axis. This fault indicates that the axis is not accurately reaching its target position within the expected tolerances or time. This is a regular monitoring function that may be deactivated in torque mode to accommodate larger position deviations inherent to that operational state.

Repair Steps

  1. 1

    Identify the specific axis number mentioned in the error message.

  2. 2

    Check the mechanical integrity of the axis, looking for excessive play in gears, backlash, or loose connections that could affect positioning accuracy.

  3. 3

    Review the motion program and path planning for the axis, ensuring target positions are reachable and motion commands are appropriate.

  4. 4

    If operating in torque mode, verify that `SET_TORQUE_LIMITS(..., monitor #off)` is configured if the regular positioning monitoring is intended to be deactivated.
