What causes Siemens SINUMERIK alarm 61549?

Dresser type parameter in grinding cycle does not match physically installed dresser. Incorrect dresser type value entered in CYCLE402, CYCLE421, CYCLE422, CYCLE423, or CYCLE424 block. Dresser configuration in machine data does not correspond to selected grinding cycle dresser type. Programmed dresser type conflicts with tool magazine or tool changer setup. Machine offset or calibration data mismatch between dresser type declaration and physical hardware.

How do I fix Siemens SINUMERIK alarm 61549?

1. Verify the physical dresser type currently installed on the machine and cross-reference with the dresser type parameter in the active grinding cycle block 2. Review the grinding cycle program (CYCLE402, CYCLE421, CYCLE422, CYCLE423, or CYCLE424) and confirm the dresser type input matches available dresser options in machine documentation 3. Check machine data and tool configuration settings to ensure dresser type definitions are correctly mapped to the grinding spindle setup 4. Compare dresser type selections across all affected cycle blocks and correct any mismatches or typos in the dresser parameter value 5. Test the corrected cycle on a scrap part or in simulation mode before running production to confirm alarm clears
