Siemens 840D 61409 - Channel block: set up offsets not present
Channel block: set up offsets not present
Alarm can be triggered by following measuring cycles: all measuring cycles. Remedy: Set MD 18112, Bit 4=1
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- MD 18112 Bit 4 not enabled for the active measuring cycle
- Setup offset data missing or not initialized in the workpiece coordinate system
- Measuring cycle called before tool offset compensation setup is complete
- Incompatible measuring cycle syntax or parameters for current machine configuration
- Tool offset table corrupted or not properly loaded at startup
Troubleshooting Steps
- 1Verify MD 18112 Bit 4 is set to 1 using the machine data editor; enable the parameter if disabled and perform a full machine startup cycle
- 2Check that setup offsets are properly defined in the active workpiece coordinate system and that the offset values are not zero or invalid
- 3Review the measuring cycle program block syntax against the documentation for your specific 840D/828D version to confirm proper parameter passing
- 4Clear any active alarms and reset the control; if the alarm persists, back up and reload the tool offset table from your machine configuration files
- 5Consult the NC program for the measuring cycle call sequence to ensure setup offsets are defined before any measurement operation is initiated
