Check Software Limit Parameters

Navigate to Setup > Machine Parameters and verify MP1410 (negative software limit) and MP1411 (positive software limit) for the affected slave axis. Ensure adequate travel range.

Always leave at least 5-10mm margin beyond the coupling position when setting software limits.

Verify Coupling Position Parameter

Check MP4120 (coupling position) for the slave axis and ensure it falls well within the software limit range defined by MP1410 and MP1411.

Never set coupling position at or beyond software limits as this will always trigger alarm 230-00D0.

Adjust Parameters if Necessary

If coupling position is outside limits, either adjust MP1410/MP1411 to expand travel range or modify MP4120 to a position within the current limits. Cycle power after changes.

Document original parameter values before making changes for easy rollback if needed.

Perform Manual Axis Movement Test

Use Manual Operation mode to jog the slave axis slowly throughout its full range. Listen for unusual noises and feel for binding or resistance.

Use reduced feedrate (10-25%) when testing for mechanical issues to prevent damage.

Inspect Mechanical Components

Check linear guides, ball screws, and coupling mechanisms for debris, wear, or damage. Verify proper lubrication of all moving components.

Pay special attention to the area around the coupling position where the axis spends most of its time.

Check Following Error Parameters

Monitor MP1230 (maximum following error) and actual following error in the axis status display during manual movement to identify mechanical resistance.

Excessive following error during slow movements often indicates mechanical problems rather than servo tuning issues.

Verify Gantry Master-Slave Assignment

Check MP4110 (gantry axis assignment) to ensure correct master-slave relationship. Verify MP4111 (slave axis number) matches the physical axis configuration.

Incorrect master-slave assignment can cause axes to fight each other during coupling.

Check Direction and Scaling Parameters

Verify MP4130 (slave direction factor) is correct (+1 or -1). Confirm MP4131 (slave scaling factor) matches mechanical gear ratios if applicable.

Use the axis position display to verify both axes move in the same mechanical direction when direction factor is +1.

Test Coupling Sequence Parameters

Review MP4140 (coupling feedrate) and MP4141 (coupling tolerance). Reduce coupling feedrate if the axis overshoots due to high speed.

Start with 50% of normal feedrate for coupling operations and increase gradually once stable operation is achieved.

Check Reference Point Status

Navigate to Position Display and verify both master and slave axes show valid reference marks. Look for 'REF' indicator in axis status.

Never attempt coupling operations without valid reference points on both axes.

Perform Reference Point Search

Execute reference point search (Setup > Reference Point) for both master and slave axes. Monitor for any error messages during the reference sequence.

Always reference the master axis first, then the slave axis to ensure proper sequence.

Verify Reference Point Parameters

Check MP1010 (reference point position) and MP1020 (reference point offset) for the slave axis. Ensure these values place the axis within its working range.

After reference point search, manually verify axis position matches expected machine position before attempting coupling.
