600-02EC

HEIDENHAIN 600-02EC - No tool found. Please check tappet diameter.

No tool found. Please check tappet diameter.

No suitable tool was found for the automatic workpiece generation. This may be due to incorrect tool geometry parameters or unsuitable tool types.

Root Cause Summary

HEIDENHAIN alarm 600-02EC occurs when the Automatic Workpiece Gaging (AWG) optimization routine cannot find any suitable tools in the tool table that match the required tappet diameter specifications. The system's optimization algorithm has determined all available tools are incompatible with the current AWG measurement cycle requirements.

Safety

  • Refer to Heidenhain service manual
  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    Access tool table

    Press MOD key, select 'Tool table' from machine operating mode menu to access tool management.

    Use CTRL+F to quickly search for specific tool numbers

  2. 2

    Check tappet diameter column

    Navigate to column 'TAPPET-D' in tool table and verify all probe tools have correct diameter values entered.

    Never guess tappet diameters - always measure with calibrated instruments

  3. 3

    Update tool parameters

    Enter correct tappet diameter for probe tools, typically 4mm, 6mm, or 8mm depending on your AWG probe configuration.

    Check probe manufacturer specifications for exact tappet diameter

  4. 4

    Validate tool status

    Ensure tool status column shows 'ENABLED' and tool type is correctly set to 'PROBE' or appropriate AWG tool type.

DIY Feasiblehigh confidence

Call a technician if:

  • ·AWG hardware malfunction suspected
  • ·Probe calibration repeatedly fails
  • ·Tool management system corruption

Prevention

  • Maintain standardized probe tool library
  • Document tappet diameters for all AWG cycles
  • Regular tool table backup and validation
  • Establish probe tool naming conventions

Common Mistakes

  • Confusing stylus diameter with tappet diameter
  • Forgetting to enable tools after maintenance
  • Using incorrect tool type designation for probes
  • Not updating tool table after probe changes
