What causes Siemens SINUMERIK alarm 61333?

_CALNUM parameter value exceeds the maximum calibration facility number defined in _CVAL[2]. GUD6 maximum calibration value _CVAL[2] set too low for current machining requirements. Incorrect calibration facility number assigned during part program or offset table setup. Machine configuration changes made without updating corresponding calibration limits. Corrupted or manually edited parameter values in machine data or part program.

How do I fix Siemens SINUMERIK alarm 61333?

1. Check current _CALNUM parameter value and compare against _CVAL[2] maximum limit in GUD6 to identify the overage 2. Review the part program block triggering CYCLE973 and verify the calibration facility number is appropriate for the operation 3. Increase _CVAL[2] in GUD6 to accommodate the required _CALNUM value, or reduce _CALNUM to stay within existing limits 4. Verify machine configuration and calibration facility definitions match current setup; restore from backup if parameters were recently modified 5. Reset affected parameters to factory defaults if corruption is suspected, then reconfigure according to machine specifications
