HEIDENHAIN 2A0-0058 - Too many points

Too many points

Maximum point storage exceeded during digitizing range creation in MDI mode. System limit is 893 points.

Root Cause Summary

Alarm 2A0-0058 occurs when the TNC control exceeds the maximum limit of 893 stored digitizing points during manual probing operations in MDI mode. This typically happens during extensive workpiece measurement or when points are not properly cleared between operations.

Safety

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

Causes and Fixes

  1. 1

    Access point memory management

    Press TOUCH PROBE key, then select 'Point Memory' from the touch probe menu to view current point count.

    Check the point counter display to see exactly how many points are stored

  2. 2

    Clear stored digitizing points

    In Point Memory menu, select 'Delete All Points' or use softkey 'CLEAR ALL' to remove all stored digitizing points from memory.

    Ensure you have saved any required measurement data before clearing points

  3. 3

    Verify point memory reset

    Confirm point counter shows 0 stored points and attempt digitizing operation again in MDI mode.

    Set up a routine to clear points after each measurement cycle to prevent recurrence

DIY Feasiblehigh confidence

Call a technician if:

  • ·Point memory clearing fails after multiple attempts
  • ·TNC software diagnostics indicate memory corruption
  • ·Alarm persists after system restart and memory management

Prevention

  • Implement regular point memory clearing in measurement procedures
  • Monitor point counter during extended digitizing sessions
  • Establish maximum point limits per measurement cycle
  • Create standard operating procedures for point memory management

Common Mistakes

  • Ignoring point counter warnings during measurement
  • Attempting to continue digitizing without clearing memory
  • Not saving measurement data before clearing points
  • Assuming point memory clears automatically between operations
