Causes and Fixes
- 1
Access Diagnostics > Tool Management on the MMC or navigate to PLC > Tool Table via NCK parameter menu. Locate tool %2 and verify the Magazine and Pot/Slot assignment is not empty or zero.
Do not confuse tool number with magazine slot—they are separate parameters.
- 2
Check SD 42300 (first tool magazine assignment base) and SD 42301 (pot/slot). Calculate offset for tool %2: Base + (Tool_Number × Magazine_Parameter_Stride). Ensure values are within valid range defined by MD 20240 (NUMBER_OF_MAGAZINES) and MD 20241 (POTS_PER_MAGAZINE).
- 3
If parameters are zero or invalid, reassign the tool to an available magazine slot via MMC Tool Management interface or reload the tool table from backup. Verify with 'TOOLCHG' PLC diagnostics screen.
