PERFORM INITIAL MASTERING <axis number>
A sensor location search or fine-tuning operation was attempted on an axis that has not completed initial mastering calibration. The axis encoder reference position must be established before any sensor-based position searches can execute successfully.
Common Causes
- System powered on after hardware replacement without running initial mastering sequence
- Robot transported or shipped without proper backup of mastering data, requiring recalibration
- Attempt to use TEACH or ADJUST function on axis with invalid or missing reference offset
- Program calls SensorLocationSearch instruction before mastering initialization block executes
- Axis 4, 5, or 6 encoder reset or replaced without subsequent mastering procedure completion
Troubleshooting Steps
- 1Access KUKA smartPAD and navigate to Mastering menu, then select the indicated axis number
- 2Execute initial mastering procedure by moving axis through full range and confirming reference mark detection
- 3Wait for mastering status indicator to show successful completion before attempting sensor search
- 4Verify that $ROBCOR.DAT contains valid reference offset values for all axes post-mastering
- 5Power cycle robot controller to load updated mastering configuration into active memory
- 6Retry sensor location search or ADJUST function on specified axis after initial mastering confirmation
