What causes Siemens SINUMERIK alarm 61372?

Selected measuring cycle variant requires SPOS (spindle positioning) capability that is not configured or enabled for the channel. Machine lacks hardware support for synchronized spindle positioning required by the chosen measuring variant. Measuring variant parameter mismatch between program requirements and actual machine configuration. SPOS functionality disabled or not properly initialized in the NC configuration. Incompatible measuring cycle selected for current spindle/channel setup.

How do I fix Siemens SINUMERIK alarm 61372?

1. Verify machine equipment includes SPOS-capable spindle and confirm it is properly configured in the machine data and channel parameters 2. Review the measuring cycle variant being called in block %2 and cross-reference against available variants that do not require SPOS capability 3. Check NC configuration files and machine data to ensure SPOS is enabled for channel %1; consult machine manufacturer documentation for correct parameter settings 4. Test with an alternative measuring variant that matches current machine capabilities; if alarm clears, confirm original variant requirements with setup 5. If SPOS hardware exists but is disabled, enable it through appropriate configuration and reinitialize the channel
