Access machine parameters

Press MOD key, select 'Machine Parameters' from setup menu, navigate to tool changer parameters group 7160-7199.

Always backup current parameters before making changes using the parameter export function.

Check MP7160 tool changer type

Verify MP7160 is set to correct value: 0=no tool changer, 1=random tool changer, 2=chain magazine, 3=disk magazine, etc.

Incorrect tool changer type can cause mechanical damage during tool changes.

Verify related tool parameters

Check MP7161 (number of tool positions), MP7162 (tool change position), and MP7163 (spindle orientation) are properly configured.

Cross-reference these values with the machine manufacturer's parameter sheet.

Cycle power and test

Perform control restart, then test tool selection with M06 command in MDI mode to verify configuration.

Always ensure spindle is empty and in safe position before testing tool changes.

Check PLC interface parameters

Navigate to MP7170-7179 and verify tool selection interface addresses are configured for your PLC system.

Document current PLC addresses before making changes for easy rollback if needed.

Verify PLC program compatibility

Check that PLC program expects the same interface protocol as configured in TNC parameters, especially for custom tool changers.

Mismatched PLC interfaces can cause unpredictable tool changer behavior.

Test PLC communication

Use TNC diagnostic screens (Setup > Diagnosis > PLC) to monitor tool changer I/O signals during selection attempt.

Look for stuck or missing handshake signals between TNC and PLC during tool change sequence.

Access tool table

Press TOOL TABLE key and verify tool entries have proper pocket assignments and tool data configured.

Use 'Check tool table' function to identify missing or conflicting tool assignments.

Check tool selection strategy

Verify MP7180 (tool selection strategy) is set correctly: 0=T number equals pocket, 1=search by T number, 2=tool name search.

Wrong selection strategy can cause tools to be loaded from incorrect pockets.

Validate pocket table

Check pocket table (if used) has proper tool assignments and no duplicate pocket numbers assigned to different tools.

Sort pocket table by pocket number to easily identify gaps or duplicates in assignments.

Check spindle parameters

Verify MP3010 (spindle type), MP3020 (spindle speed range), and MP3030 (spindle orientation) parameters are configured.

These parameters must match the actual spindle hardware specifications exactly.

Verify tool clamping parameters

Check MP3040-3049 series for tool clamping configuration, including clamping force and timing parameters.

Incorrect clamping parameters can result in tools falling out or being damaged during machining.

Test spindle functions

Use MDI to test M19 (spindle orientation) and verify proper spindle positioning for tool changes.

Monitor spindle encoder feedback during orientation to ensure consistent positioning.
