Access machine parameters

Press MOD key, enter machine parameter access code, navigate to General > All Parameters or use search function for MP110

Machine parameter changes require proper authorization and may affect machine behavior. Document original values before making changes.

Check MP110 axis configuration

Examine MP110 for each channel. Verify that rotary axes (A, B, or C) are assigned. Value should indicate axis type (e.g., 'A' for rotary around X, 'B' for rotary around Y, 'C' for rotary around Z).

On iTNC 530 and TNC 640, also check MP1010 to ensure the number of axes includes your rotary axes in the total count.

Verify kinematics parameters MP7500 series

Check MP7500 (KinematicsOpt) for proper kinematics type selection. Verify MP7502 and MP7503 define rotary axis positions and orientations in the kinematic chain. For swivel head machines, check MP7510 (type of rotary axes).

Use the built-in kinematics configuration assistant on TNC 640: Settings > Kinematics Config to validate your setup graphically.

Configure axis assignment in MP100 series

Ensure MP100-109 (axis assignments) map rotary axes to physical drive channels. Each rotary axis needs a dedicated channel assignment.

After changing axis configuration parameters, a control reboot is required for changes to take effect.

Test rotary axis movement

After configuration, switch to Manual operation mode and test rotary axis movement using the axis direction keys. Verify each rotary axis responds correctly and displays position feedback.

Test with reduced feedrate override and ensure tooling and fixtures are clear of collision hazards.

Review NC program for orientation commands

Open the program in Edit or Program Run mode and search for PLANE SPATIAL, PLANE VECTOR, M128, M114, M116, or TCPM keywords. Also check for Cycle 19 WORKING PLANE or Cycle 800.

Use the TNC search function: Press GOTO, then enter 'PLANE' or 'M128' to quickly locate orientation commands.

Identify tool orientation requirements

Check if the program was generated by CAM software with 5-axis post processor settings. Look for TX, TY, TZ tool vector components in linear blocks or F_NORM functions.

If this is a ported program from a 5-axis machine, you may need to re-post process with a 3-axis configuration or manually edit to remove orientation changes.

Remove or modify orientation commands

For 3-axis operation, comment out or delete PLANE SPATIAL commands and replace with PLANE RESET. Remove M128 TCPM activation. If using tilted working plane, replace with fixed PLANE AXIAL with manual head positioning.

Removing orientation commands may change tool contact points. Verify tool paths remain collision-free and machining results are acceptable.

Verify machine configuration matches program

Consult machine documentation to confirm whether rotary axes are physically present. If they exist but aren't needed for this job, reprogram without orientation features.

Create separate program versions: one for 3-axis mode and one for 5-axis mode if your machine has optional rotary axes that can be configured.

Access kinematics configuration

Navigate to MOD > Machine Parameters > Geometry/Kinematics. On TNC 640, use Settings > Kinematics Config menu for graphical configuration interface.

On iTNC 530 and newer, the graphical kinematics editor provides visual feedback showing your machine configuration, making errors easier to identify.
