Channel block no memory left for tool/magazine data

The values of the following tool/magazine data variables in the NC are given by machine data: - Number of tools + number of grinding data blocks: 18082 MM_NUM_TOOL - Number of cutting edges: 18100 MM_NUM_CUTTING_EDGES_IN_TOA Tools, grinding data blocks, cutting edges can be used independently of the

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Machine data 18082 (MM_NUM_TOOL) set too high relative to available system memory
  • Machine data 18100 (MM_NUM_CUTTING_EDGES_IN_TOA) configured larger than memory allocation allows
  • Combined tool database, grinding data blocks, and cutting edge definitions exceed allocated memory pool
  • Tool magazine data structure corruption or fragmentation consuming excessive memory
  • System memory degradation or allocation conflict with other NC functions

Troubleshooting Steps

  1. 1Check current values of MD 18082 (MM_NUM_TOOL) and MD 18100 (MM_NUM_CUTTING_EDGES_IN_TOA) against machine documentation and available system RAM specifications
  2. 2Review tool table usage: count actual tools, grinding data blocks, and cutting edges currently in use versus configured limits
  3. 3Reduce MD 18082 and/or MD 18100 values incrementally to free memory, then reload tool data and test block execution
  4. 4Clear tool magazine data and rebuild from known good backup or minimal configuration to eliminate corruption
  5. 5Verify no competing memory allocation issues by checking other NC machine data memory-related settings and clearing unused macro definitions or parameters
