Siemens 840D 6200 - Memory for CC MD full.

Memory for CC MD full.

The memory reserved for storage of compile cycle machine data is full. Some of these machine data could not be created correctly.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Excessive number of custom machine data parameters created without cleanup
  • Multiple tool offset tables or workpiece offset tables defined beyond system requirements
  • Corrupted or orphaned machine data entries consuming reserved memory space
  • Firmware updates that reallocate memory partition sizes without clearing legacy data

Troubleshooting Steps

  1. 1Access machine data editor and review all custom CC MD parameters for obsolete or duplicate entries; delete unnecessary parameters to free memory
  2. 2Back up current machine data configuration to external storage, then perform a machine data reset to factory defaults and selectively restore only required parameters
  3. 3Check SRAM battery voltage and condition; low battery can cause data corruption; replace if voltage reads below manufacturer specification
  4. 4Verify control unit firmware version matches the machine tool documentation; if mismatch exists, consult Siemens service bulletins for memory allocation changes between versions
  5. 5If issue persists after cleanup, perform a complete machine data initialization through startup and commissioning procedures to rebuild the CC MD partition
