Access Machine Parameters

Press MOD key, enter machine manufacturer password, navigate to 'All' or 'CfgAxes' section to access MP7500 series parameters.

Incorrect machine parameters can cause collision or unexpected machine behavior. Document current settings before changes.

Review MP7500.x Settings

Check MP7500.0 through MP7500.x for each rotary axis. Bit 0 = 0 means workpiece side, Bit 0 = 1 means tool side. Identify which rotary axes are involved in your transformation.

MP7500 uses axis index numbers, not names. Verify axis index assignments in MP100 through MP109 first.

Correct Carrier Assignment

For the rotary axis causing the alarm, modify MP7500.x bit 0 to assign it to the tool side (set bit 0 = 1). This must match physical machine construction.

Only change this if the axis is physically mounted on the tool-carrying spindle head. Incorrect assignment will cause transformation errors.

Restart Control

Exit MOD function and perform a control restart (PLC SYSSTART) for machine parameter changes to take effect fully.

After restart, verify settings with FUNCTION TCPM TEST or manual movement in transformed mode before automatic operation.

Identify Active Kinematics

Press 'PGM MGT' button, navigate to TNC:\table directory. Check which *.kin file is active or recently selected via SEL KINEMATICS or CYCL DEF 19 PLANE.

Use 'Additional Info' soft key on *.kin file to view when it was last activated and by which program.

Examine Kinematic File Content

Open the *.kin file in editor mode. Look for AXES: section and carrier assignments (HEAD or TABLE keywords) for rotary axes. Compare against physical machine configuration.

Do not edit manufacturer-supplied kinematics files without backup and proper documentation.

Verify Rotary Axis Carrier Tags

In the *.kin file, ensure rotary axes required for transformation are tagged with 'HEAD' carrier assignment, not 'TABLE', if the transformation requires tool-side axes.

Search for lines containing your rotary axis names (typically C, A, or B) and verify the associated 'carrier=' parameter.

Select Correct Kinematic Preset

If multiple *.kin files exist, use SEL KINEMATICS command to activate the correct kinematic model matching your current machine configuration and operation requirements.

Many machines have separate kinematics for head rotation versus table rotation configurations. Verify you're using the correct preset.

Verify Physical Machine Configuration

Physically identify whether rotary axes (A, B, C) are mounted on the spindle head assembly or on the workpiece table. Consult machine documentation if uncertain.

Misidentifying axis location can lead to incorrect parameter settings and potential collisions.

Review NC Program Transformation Calls

Check NC program for FUNCTION TCPM, M128, PLANE SPATIAL, or CYCL DEF 19 PLANE commands. These require tool-side rotary axes for proper TCP transformation.

Use 'Test Run' mode with FUNCTION TCPM TEST to simulate transformation behavior before executing actual cuts.

Switch to Compatible Transformation Method

If rotary axes are table-mounted, use alternative programming methods: manual tilting with PLANE AXIAL or use 3+2 positioning instead of continuous 5-axis TCPM modes.

For table rotary machines, PLANE AXIAL with M228 (tool length compensation in tilted plane) is often the correct approach instead of M128.

Consult Machine Manufacturer Documentation

Review machine-specific kinematic documentation from manufacturer to confirm supported transformation modes and proper SEL KINEMATICS selection for your operation.

Machine manufacturers often provide sample NC programs demonstrating correct kinematic activation for both head and table rotation configurations.
