Access Machine Parameter Editor

Press MOD key, select 'Maschinen-Parameter', enter password (typically manufacturer password required). Navigate to MP7160x series parameters.

Machine parameter changes require manufacturer authorization. Incorrect settings can cause collision or machine damage.

Verify Vertical Axis Assignment

Check MP7160 (or MP7162) for vertical axis designation. Standard configuration: MP7160=2 for Z-axis as vertical. Verify this matches your machine's physical build orientation.

Validate Axis Direction Vectors

Review MP100-MP130 CfgAxisKeys entries. Ensure axis assignment matches machine coordinate system. Z-axis should have correct polarity (+/-) matching machine build documentation.

Compare current MP settings with machine acceptance documentation or contact machine builder for original parameter set.

Perform Control Restart

After parameter correction, perform controlled shutdown: MOD > soft-key 'Ausschalten'. Wait for complete shutdown, then restart control to initialize new axis configuration.

Check Active Kinematic Configuration

Navigate to MOD > Maschinen-Parameter > Kinematik. Review active kinematic type (table, nutating, swivel head, etc.). Verify kinematic description matches actual machine configuration.

Use soft-key 'Kinematik simulieren' to visualize current configuration before making changes.

Verify Rotary Axis Orientation Parameters

Check MP7502x (rotary axis base vectors) and MP7503x (rotary axis direction vectors). These define how rotary axes affect vertical axis calculation. Incorrect vectors cause orientation errors.

Kinematic parameters are machine-specific. Use only values provided by machine manufacturer.

Test at Known-Good Position

Move rotary axes to zero position (typically A=0, B=0 or C=0). Reset transformation with PLANE RESET in MDI mode. Retry operation to isolate if error is position-dependent.

Update Kinematic Table

If using kinematic table (*.tab file), verify table entries using editor in TNC. Check for proper format and complete definition of all transformation points. Reload table using KINEMATIC SELECT command.

Identify Active Transformation

In Manual mode, check status display (bottom screen area) for active PLANE or coordinate transformation. Note transformation type and angles. Press 'POS' soft-key to view detailed transformation status.

Review NC Program Plane Definition

Open NC program in editor, search for PLANE SPATIAL, PLANE VECTOR, or CYCL DEF 19 commands. Check spatial angles—combinations creating tool axis parallel to Z-axis (±90° combinations) cause this error.

Use TNC test run with graphic simulation to identify exact block where transformation becomes invalid.

Reset Transformation

In MDI mode, execute 'PLANE RESET' followed by 'M02'. This clears all active tilting transformations. If alarm clears, root cause is in transformation programming.

Modify Spatial Angles

Adjust PLANE SPATIAL angles to avoid singularity. Ensure tool axis never becomes exactly parallel to defined vertical axis. Maintain minimum 5° separation from parallel condition.

For challenging geometries, use PLANE PROJECTED instead of PLANE SPATIAL to let control calculate valid orientations automatically.

Verify Software Version

Press MOD key, select 'Service', then 'Version'. Note TNC software version and NC software number. Compare with pre-update documentation.

Software version changes may require parameter adaptation—consult Heidenhain technical bulletin for your specific version.
