Channel block: Shoulder height of grinding wheel must be >
The alarm can be triggered by the following grinding cycle: CYCLE432 Remedy: Change shoulder height or grinding wheel radius
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- Grinding wheel radius exceeds maximum allowable value for current shoulder height setting
- Shoulder height parameter configured below minimum required threshold for active grinding wheel
- Incorrect wheel geometry data entered in CYCLE432 parameters
- Grinding wheel wear has reduced effective radius below specification, requiring shoulder height adjustment
Troubleshooting Steps
- 1Verify current grinding wheel radius and shoulder height values in CYCLE432 cycle parameters for the affected channel and block
- 2Compare wheel radius against shoulder height requirements; wheel radius must be less than shoulder height value
- 3Measure actual grinding wheel diameter with calipers and update wheel geometry parameters if wear is present
- 4Adjust shoulder height parameter upward or reduce grinding wheel radius value to satisfy geometric constraint
- 5Clear alarm and execute test block after parameter correction to confirm resolution
