Common Causes

• Array field size mismatch between _TP, _WP, _KP, or _TWP declarations and their corresponding _CVAL index references
• Measuring cycle attempting to access _CVAL array index that exceeds declared array bounds
• Probe calibration data arrays not properly sized to accommodate all measurement points or tool offsets
• Incorrect dimensioning of workpiece or tool probe arrays in part program or machine parameters
• Measuring cycle block referencing tool probe (_TP), workpiece probe (_WP), kinematic (_KP), or thermal compensation (_TWP) data with undersized storage arrays

Troubleshooting Steps

1. 1Verify the declaration size of the failing array (_TP, _WP, _KP, or _TWP) in the part program and machine parameter files matches the number of elements being accessed by the measuring cycle
2. 2Check the _CVAL index value referenced in the alarm message (0 for _TP, 1 for _WP, 2 for _KP, 3 for _TWP) and confirm it does not exceed the array upper bound
3. 3Review the measuring cycle block number shown in alarm parameter %2 and cross-reference the probe type and measurement requirements against array declarations
4. 4Increase the array dimension in the parameter or variable declaration to accommodate all required calibration points, offsets, or thermal compensation values
5. 5Execute a manual dry-run of the measuring cycle after correcting array sizes to confirm the alarm is cleared and probe data is stored correctly
