HEIDENHAIN 200-001B - Configured direction for axis invalid

Configured direction for axis invalid

The indicated axis lacks a valid direction assignment. None of the standard directions XAxis, YAxis, or ZAxis has been configured for it.

Root Cause Summary

HEIDENHAIN alarm 200-001B occurs when an axis is defined in the machine parameters but lacks proper directional assignment (XAxis, YAxis, or ZAxis configuration). This typically happens during initial machine setup, after parameter restoration, or when axis configuration parameters become corrupted.

Safety

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

Causes and Fixes

  1. 1

    Access machine parameter menu

    Press MOD key, enter machine parameter mode, navigate to General Machine Data section.

    Ensure machine is in safe state before accessing parameters

  2. 2

    Check axis configuration parameters

    Verify MP1010.x AXIS_NAME parameters for the affected axis. Ensure proper assignment to X, Y, or Z direction.

    Cross-reference with machine manufacturer's parameter documentation

  3. 3

    Correct axis direction assignment

    Set the appropriate axis direction parameter (XAxis=0, YAxis=1, ZAxis=2) for the affected axis number.

    Incorrect assignment can cause dangerous machine movement

  4. 4

    Perform parameter reset and restart

    Execute parameter validation, perform controlled restart to activate changes.

    Document original parameter values before making changes

DIY Feasiblehigh confidence

Call a technician if:

  • ·Parameter corruption persists after multiple restoration attempts
  • ·Machine exhibits unexpected movement after parameter changes
  • ·Software version compatibility issues require specialized knowledge

Prevention

  • Regular parameter backups before any changes
  • Verify parameter integrity after software updates
  • Document all axis configuration changes
  • Use parameter validation functions before system restart

Common Mistakes

  • Confusing axis numbering with direction assignment
  • Restoring incomplete parameter backups
  • Changing parameters without proper documentation
  • Ignoring parameter cross-reference consistency
