Siemens 840D 61526 - Channel block: Workpiece radius = 0
Channel block: Workpiece radius = 0
The alarm can be triggered by the following grinding cycle: CYCLE414 Remedy: Enter workpiece radius > 0
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- Workpiece radius parameter set to zero or not initialized in CYCLE414
- Incorrect part program setup failing to define workpiece geometry before cycle execution
- Parameter input error during manual cycle entry or job setup
- Machine offset or workpiece datum configuration missing required radius value
Troubleshooting Steps
- 1Verify CYCLE414 parameters in the part program and confirm workpiece radius value is greater than zero
- 2Check machine operator panel input fields for radius entry - re-enter valid positive workpiece radius value
- 3Review part program syntax around CYCLE414 call to ensure radius parameter is properly defined before cycle execution
- 4Inspect machine configuration files and workpiece setup data to confirm all required geometric parameters are loaded
- 5Execute single block mode to isolate the exact program line triggering the alarm and validate all input parameters
