    Check the physical positive limit switch for the affected axis for any damage, obstruction, or incorrect adjustment.

  2. 2

    Verify the setting of parameter MP650 (Positive software limit switch) for the specified axis to ensure it is configured correctly according to the machine's travel limits.

  3. 3

    Inspect the axis position feedback system (encoder) for accuracy and potential errors that could lead to an overshoot.
