Channel block: Chamfer / radius + shoulder height are less than
The alarm can be triggered by the following grinding cycle: CYCLE432 Remedy: Check values in grinding wheel data
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- Chamfer or radius value is too small relative to the shoulder height parameter in CYCLE432
- Shoulder height parameter exceeds the sum of chamfer/radius dimensions in the grinding data
- Incorrect wheel offset or grinding wheel data entries causing dimensional conflicts
- Grinding cycle parameters not updated after wheel change or dressing operation
Troubleshooting Steps
- 1Verify the chamfer/radius and shoulder height values in the CYCLE432 grinding wheel data match the physical wheel geometry
- 2Check the grinding wheel offset and ensure it reflects the current wheel diameter and dressing state
- 3Review the part program block referenced in the alarm message for parameter consistency
- 4Compare current grinding data against the machine's grinding wheel database to confirm values are within acceptable limits
- 5Re-execute the grinding cycle after correcting the dimensional parameters in CYCLE432
